    "Houses could also use heat pumps that run on renewable electricity, district heating, electric heating or solar thermal systems

    "We're starting comparatively late with this. Other countries have done this earlier," Habeck said

    Around 78% of Germans are against the planned law, a survey by Forsa pollster published by ntv and RTL broadcasters showed on Wednesday.

    Posted By: WillInAberdeenGermany to ban new and replacement gas boilers from next year

    If the law sticks I can see a lot of 5 - 10 year old gas boilers getting junked this year.

    Posted By: WillInAberdeenThe government will offer a subsidy of 30% for residential properties occupied by owners and 10% extra if the owners opt for an earlier climate-friendly heating switch...

    Hmm - And landlords ? Never mind they can just put the rent up to cover the costs.

    Of course Germany has been affected to a much greater extent by the lack of Russian gas than the UK - which loss I suspect has been the main driver for this change.

    Perhaps more unavoidable than 'enlightened', with gas supply dwindling. And closing last three nukes this w/e too. No doubt then (or already) importing elect from French nuclear.

    Maybe rash and compromised, but right now the whole world should be holding nose, closing eyes and taking the jump, just like this!

    My understanding is that this covers where a boiler might break and be BER (or any sort of repair).

    It is at that point impossible to quickly get a heating system working in the property again. Equally, the cost of replacing a Boiler with a HP system is at least 2x greater, possibly more. How would that be paid for.

    The burden will fall on landlords to a much greater extent than here is the UK as a much higher proportion of Germans rent rather than are owners, but still, rapid replacement or a boiler with a HP simply is not an option.

    OTOH, forcing repair where otherwise it may have been scrapped, might be a good thing.

    I'd have thought in that situation, landlords would fit plug in panel heaters, rather than heat pumps, EPCs permitting. That's what happened while we were renting when the boiler self-destructed.

    One reason heat pumps are expensive is because the market is niche and there are not enough suppliers and fitters. The 1000s of German gas heating fitters are probably now seeing their livelihoods disappear in front of them, and seriously thinking about moving into the heat pumps market.

    As more homes move off gas, the remaining pool of customers will have to pay the overheads of running the gas distribution network. Be interesting how much that pushes up standing charges.

    Ironically the German electricity grid is much dirtier than UK, lots of coal power and no nuclear, so direct electric heating is actually still worse for carbon than gas boilers.

    The Green party are propping up the government in Scotland same as in Germany. On a smaller scale, the politics are similar around the proposed tax/deposit on bottle recycling in Scotland - ideas were promised in manifestos which have to become practical in government, while keeping the coalition together. (The deposit scheme was popular in principle, but had to be delayed when the practicalities became difficult, cue much acrimony.) Wonder how this will play out in Germany.

    It seems that they are talking about a boiler scrappage scheme.

    However it seems that the story can be spun two ways - hence the headline of the article below:
    "German government settles heating row, relaxes rules on new fossil fuel systems"

    https://www.cleanenergywire.org/news/german-government-settles-heating-row-relaxes-rules-new-fossil-fuel-systems

    Reading that article AFAICS it has watered down the proposal to a non-event.
    e.g.
    H2 ready gas boilers can be installed
    Blue H2 is supported by the regulations as is wood burning and pellet boilers.
    And

    quote
    No one should be overburdened when replacing their heating system, economy minister Robert Habeck told broadcaster ARD, adding that social hardship is to be compensated for with subsidies. Exactly how that will look like is yet to be decided.
    end quote

    So enough scope to drive a horse and cart through the legislation and lots of options to modify the plans in the future.

    Until the alternatives are as cheap and easy as a gas combi then there is going to be (a lot of) push-back.
    IMO this push-bach is going to happen across the board.

    Modern gas boilers are much more advanced than those of 50 years ago - just like the developments in cars over the years and prices have risen to match However as an alternative to the ubiquitous gas combi electric heating is cheap to install but all the time electricity is pegged to the price of gas it is (too) expensive to run. Solar and wind give cheaper electricity than gas - with costs still falling - so there could (will?) be a time when resistance electric heating is a reasonable option even for retrofit in older buildings. - just IMO

    Was that the Isle of Man version?

    Different sources suggest that a 1916 Model T ford (21mpg, 45mph) cost the equivalent of 3 to 5 years of the average income of the time, so equivalent to about Ă‚ÂŁ100k - Ă‚ÂŁ150k today. So as with most things, cars have got better and more affordable since their early days! Probably took until 1980s for as many people to afford a car as can today.

    Last time I looked, the lifetime cost (Total Cost of Ownership) of a heatpump is about the same as a gas boiler, because the higher upfront cost is balanced by lower running costs for fuel, standing charges etc.

    Obvs that depends how much heat you use, and whether you expect the relative cost of electricity to go up or down compared to gas. And agreed that people fixate on the upfront cost, when actually the running costs add up to a lot more Ă‚ÂŁ over the lifetime of the boiler. Similar to the situation with electric cars (back to Ford again!)

    But when you are talking about landlords - of any sort, private, housing ass. or state - the upfront cost has to be found and it is the tenant who benefits from lower running costs. (A bit like insulating the property) The solution tends to be to put up the rent.
    I have found in the main that the headline rent is what counts and the running costs tend to be ignored.

    Sorry, I got mixed up -don't understand how :cry: I should have been referring to 1923 (the Model TT didn't start production until 1917 apparently) at which time its price was $380 FOB Detroit (see http://www.oldcarbrochures.com/static/NA/FMC%20Trucks-Vans/1923_Trucks/1923_Ford_Truck_Foldout/1923%20Ford%20Truck%20Foldout-02-03.html ). The average annual salary-wage of all nongovern­mental nonagricultural employees (full-time equivalents) for 1923 is $1428 (see p23 of https://fraser.stlouisfed.org/title/war-postwar-wages-prices-hours-1914-23-1939-44-4318 ) so clearly wages > price of TT rather than the other way around. Indeed the reason the price came down after the product was released was because of the large volumes sold because of its relative lack of expense.

    But I wasn't talking about affordability, rather just the cost. And specifically I was thinking of a heat pump versus a gas boiler, in terms of its cost and complexity.

    PIH, i’m a landlord and have contact with lots of others, we all let property towards the benefits end of the market.
    In 27 years of letting , i’ve only had 1 tenant who took any interest in how to get the best from a heating system, all the rest just want radiators that get hot enough to glow in the dark. Wireless thermostats/programmers invariably have flat/ no batteries in them, are never set to correct time or programmed. Temperature regulation is a mixture of open windows and or boiler off. They generally moan in mid winter that the heating is expensive , but have no idea of what they’ve spent over the preceding year, just that in a week where the temperature has’nt been over zero they’ve had to top up twice.
    As and when i’m forced down the heatpump route, in the absence of a serious education programme from the gov, i’ll be getting endless calls about flat not being warm enough ( all but 1 are currently epc C) and they’ll have tinkered with any controls they can in an attempt to get more heat.
    I’ve an ex council flat , that has an old back boiler installed in 1988 and weather compensation , despite the appalling published efficiency rating and pilot light , the flat costs very little to heat. It’s the only 1 of 2 out of 18 that haven’t had combis fitted, the combis fitted by the council because they never looked after the back boilers.
    When i have to move over to heatpumps ( if it’s actually a realistic possibility for the buildings i have) i’ll need to move over to UFH ( current heating is radiators via plastic microbore) or go for IWI, either way it means new kitchens, bathrooms, flooring and decoration on top of the iwi / ufh and heatpumps. Plus finding a way for hotwater . I did a rough costing for a block of 4 small flats built in 2004, it came out at 80-100k , when you factored in lost rent and the council tax and utility costs whilst empty. I’d want that back over 7-10 years which with finance costs means the rents would be going up 200-250 a month, which is unaffordable on rents that are currently 650-725 a month , for the tenants who are on lower incomes.
    The costs to the taxpayer for grants to the social housing sector ( to improve energy efficiency and pursue net zero) in the years to come are going to eyewatering and hugely unpopular for those homeowners who’ll be looking at what needs to be done to their own homes.
    The proposed improvements to energy efficiency required of the private rented sector appear have been kicked into the long grass, the previous consultation has had no response from the gov and is all reality no longer valid with the energy cost increases of late. There is no joined up thinking or long term plan and to cap it off until there is legislation that forces landlords to improve their property any improvements a landlord may make , would currently be classed as capital improvements and not a business expense, as a result such tax treatment and the lack of some long term certainty as to what work is required , hardly any landlord is going to spend the sums of money needed.
    Total mess.

    In no particular order,

    There needs to be legislation/guidance for landlords that reaches at least 10 preferably 20 years forward , as the costs involved are such that there needs to be certainty, costs need to be tax deductible in several ways and landlords then choose which they prefer.
    The social sector needs to be treated identically to the private sector, that way the cosy deals and excessive subsidies will be curtailed.
    Tenants have to expect to save nothing , the reduced bills will go to the landlords be they private or social to repay the expenditure.
    There needs to be a proper education campaign as to how to heat your home in the most efficient way, education system , councils, energy suppliers etc all need to be involved. But only ending up worse off will concentrate minds, which is hardly a way forward.
    Interest free loans would be nice but that’s never going to happen, quite how i’ll cover the cost for my properties is going to be a real issue , as my tenants can’t afford the rent rises the expenditure would need, plus my properties being all C’s bar 1 D are not going to save much going the heat pump route, certainly not the 3k a year rents go up.

    Which is why i’ve just had my epcs redone, i’ll have 10 years to see how things unfold. ( and save). The other forgotten aspect is that there are huge numbers of competent experienced gas engineers, i’ve used the same one for 15 years, lots of self employed independent engineers you can build a rapport with and get good service, i’ve no confidence i’d find anything vaguely similar in the heatpump arena and have to use companies with all the added costs and so larger bills they incur.

    It won’t sit well with many on here, but the current path is going to be a disaster, had the sustainability building codes not been discarded the country might now have a much more experienced and larger green oriented construction industry, instead we still have hordes of housebashing bodgers. There should be a drive to improve buoldings insulation ( the old days of £1 rolls of insulation and an advertising campaign to get people to use them) scrap vat on all energy efficency related products for everyone no matter where they buy it. Do something about the “at the till prices” which have soared for insulation products.

    Again won’t go down well on here, net zero is a 50 year marathon not a sprint and for all intents and purposes in the real world of your average home owner the starting gun hasn’t fired. There’s too great a fixation on the eventual goal and next to no consideration of what needs to be done at street level to get there, instead the numpties in parliament and the civil service dream up impractical unnaffordable timelines.

    Thanks for the feedback. I think the chances of 10 or 20 years of stability is a hopeless dream. The rental sector and leasing law in general is in such a mess that needs sorting out and that will involve banging a lot of heads so nobody is keen to do it.

    I think landlords in general would be better regarded and treated if they behaved better themselves. (ditto tenants FWIW). There are too many cases of obviously poor behaviour on all fronts for any external observer to have much sympathy for any of the guilty parties and by extension whole groups get tarred with the same brush.

    Agree about the lack of properly trained people (same in the health service, the civil service, the justice department etc etc). Government mismanagement at all levels.

    Agree about the marathon rather than a sprint; the problem is that the end date is pretty much fixed (or a lot less flexible than you might hope). So we need some very competent project planners who are actually listened to, and who can actually be trusted to do something we can all live with.

    DJH, the rental sector is pilloried for the actions of a minority of criminal landlords, but there’s no appetite or will to root them out and deal with them. Largely because ( in general) they house some of lifes least fortunate and problematic tenants that no one else wants.
    The nations housing has descended into farce and the gov needs a whipping boy, the prs is a convenient victim and the actions against it based on the actions of the criminal few that the state doesn’t want to deal with.
    The social sector is way worse than the private , how many people has it killed ? ( lakanal, grenfell, victims of cold and mould) if it were the private sector it’d have been crushed with legislation. Only this week we hear of a social housing tenant who’d lain dead for 6 years. How on earth is that possible? No check on the benefits that were paid all that time.
    As for leasehold, it basically comes down to money. There’s no justification for groundrent , and the management of leasehold properties needs regulationg properly, leases should be for 999 years and so virtually freehold. However the main problem is that legislation of all sorts means that managing a building properly is expensive, but the leaseholders too often feel it can be done on a shoestring. Even if leasehold is reformed the problem of who manages and building ( and takes responsibility remains) , again the social sector is abysmal , how on earth it was allowed that in part rent part buy schemes the owner / leaseholder became responsible for all the costs is abhorrent.
    As for time scales of stability, is it too much to ask for 10 years plus if i’m expected to invest 15% of a buildings value in upgrading the efficiency/ heating , the social sector will be getting grant funding at some point and will spend 10’s of billions all funded by the taxpayer, i and other landlords just want a bit of certainty.
    The UK paupering itself in a headlong pursuit of net zero is going to do nothing to save the planet and is little more than truly grandiose virtue signalling, it will always be a marathon and if there truly isn’t 50vyears to run it , then the game is up anyway , the rest of the planet will largely do as it will and watch us in amusement. The nation just doesn’t have the wealth to achieve the goal our government has set it, we won’t be able to borrow enough and the parlous state of the nations services are going to have a much greater need to be addressed.
    I read the thread about suggested policies for a green party councillor, lots of lofty ideals, but largely non starters , if the nation really wanted to sort itself out it’d make being fat , illegal. It’d do far more for the nations health than net zero, air quality and ever expanding health spending ever would and make us more productive.
    But obviously is not reasonable or acceptable.
