We’ve got Hive to control the heating but I’ve been thinking about getting some of their smart TRVs (turn down/off bedrooms during the day for example). Anyone have experience of these or similar? Are they worth it? They are quite expensive, so wonder what, if anything, I could save long term from using them.

Does it even make sense to have the heating off in different rooms at different times of the day? Without meticulously closing every door in the house at all time (not going to happy with young kids around), would it end up a bit of a false economy?

    Bicky We used to have hive system and please with it do decided to get smart radiator valves for all 13 radiators and regret it. They take long time to open up and start heating - even ¾ minutes. Had issues with automatically changing temperature and switching off during boost.

    since replaced with Tado with valves and they are so much better. Radiators get hot almost immediately and had no issues since.

      LMSC …. and I’ve just been sent an mail from British Gas offering me a 2-year fix for £3900! Sounds like I’d be getting a bargain 🤣

      i think its a total con this quarterly review, they say they can react to raises and falls, but we all know it wont fall, what it will be is a o shit reaction to the 80% increases we are seeing, and will be 15% each time

      im tempted to fit a log burner and a flue

      The energy companies would typically have a long-term contract to buy and distribute energy at a rate agreed in advance. The rates are normally fixed at the time of a contract, unless they buy at the cash or spot or options market. It is also possible, they lock-in their price at different contract maturities after assessing their fixed / variable contract price with us. Either way, significant risks are involved under current circumstances.

      So, they will also be hedging their energy to protect against any adverse movements. One needs to have a fairly good view of where the market is moving to make the hedge profitable or reduce the losses. The longer the cap, the longer the hedge, the greater the degree of accuracy required and greater the risk. That’s why the suppliers will have a bigger margin to offset the difference in their buying and selling prices — think currency rates.

      while the shorter cap is itself a good idea to provide some dynamism and reduce the risk, the risks reduction should work both ways. It can’t be seen helping only the producers and leave the consumers high and dry.

      I think the fix we all get could have a clause (like options contract) to benefit from lower prices. It will be attractive to have options built in the fixed deal. One will be paying a little additional premium to have the options built into the contract as the supplier is taking a risk of we cancelling the fixed contract and put in place a new contract.

      The fixed contract gives a certainty to us and the supplier as the latter would know exactly the selling price for a set period of time. The built-in options will reduce the certainty from the supplier side.

      Of course, the options are very risky and am simplifying the complex area at a high level to give an idea.

      I was thinking, as I do…you can get a big battery and a 4 or 6 kW inverter, and then find a tariff like ’octopus go" or whatever it is which has a cheap rate for 4 hours during the night. If you could fix on a tariff like that for 2 years or whatever then you could charge up an 8 or 9 kW battery overnight in that 4 hours that’s like 4 times less than the normal electric rate then use that during the day because you can’t charge the battery above a certain rate you can charge electric car as well during the cheap rate. I actually think the payback would be quicker than solar PV and of course you wouldn’t have to have the solar PV panels installed. Just a battery plus inverter. Of course the bastards would probably get rid of cheap rate before you got payback!

      I checked out the octopus go tariff and the electricity is approximately 4 times cheaper than the normal uncapped rate currently yeah but the higher rate is 10 p more expensive than the uncapped rate but as I say if you could run off a battery that you charge during the cheap rate you could be saving 75% on your electric costs.

      Bicky The other thing to consider is the extent to which you’d be getting condensation (and mould/mildew) issues if you have too strong a temperature gradient in the house. Many moons ago we “closed” a couple of rooms that we didn’t use, and we had to re-open them PDQ because of that…

      Don’t mean to scare you out or anything - this was in an old Victorian house, on a lower ground (half-basement), and the effect may well have been very different in a different house or even just on another floor, where there wasn’t so much humidity and greater airflow. Just be aware that it can happen - independent of what system one uses (we had “old” mechanical TRV).

      prezes Ref the tado radiator heads £ 70, presuming these fit onto the existing valve body, you will still be relying on the old / original thermostatic capsule ? These deteriorate with age / lack of adjustment.

      It does call into question the efficacy of the new heads on old bodies .

      Also important to have boiler and system maintained including flushing and replacing inhibitor.

      My local Esso independent is selling E10 at 169.9 today, Leatherhead Tesco and everyone else is 177.9, the difference between Leatherhead Tesco and Gateshead Costco is 18p a litre, substantial.

      If you have an old school gas meter can you submit higher meter readings and pay already before the price hike? It’s sort of same logic with a prepayment meter in theory isn’t it. Would that be legal?

        Inspector I’m pretty sure there is no specific law that deals with exactly this. There is no theft but there may be fraud - you would be lying about usage to date. Can’t imagine it would ever make it to court - too busy dealing with crime to bother about somebody pre-paying for utilities.

        So as with so many things - it’s grey. Your chances of getting away with it are directly related to how much gas you attempt to pre-pay for.

        I may know someone who did this with electricity prior to the last hike. It worked out fine for him. :-)

          Yea, if I had a prepayment meter this would have been totally legal but now as you say it’s grey. And nothing also on Google about this apart from few Reddit discussions.

          Best guess you would be fine providing you did not over do it and a meter reader never visited before you had used your credit

          We pay by DD but asked for our monthly payment to be increased, deliberately to build a bit of credit before the winter so the bills won’t be such a shock. Spreading the cost a bit right, and with the £400 coming our way I’m hoping I can continue to pay what we are now through the winter. We shall see 😬
