We've have tenants that struggle with a combi boiler and a single non-programmable thermostat! Complained hot water wasn't working at various times. Eventually worked out they were turning the boiler off at the wall when they didn't want heating. <Facepalm> Then there was the lady who complained her heating was erratic, sometimes not coming on when she wanted it. Quickmcheck showed no problems. Then I asked to see the thermostat. "What's that?" - I described it. She looked puzzled then rummaged around in a kitchen drawer, pulled it out and said "oh you mean this?". She didn't know what it was, so stuck it in her random drawer of stuff.....next to the oven! Heating wouldn't come on for a couple of hours after after she'd cooked! 😂 The ideal would be two buttons "I am too hot" and "I am too cold"!

I have got a quote for that. I'd keep the hot water system as is (electric shower and immersion tank - though I may ditch the immersion tank for a direct water heater) I am tempted My only concerns are 1) the Daikin units show a minimum external temp of -15C. We don't get that temp very often, maybe once every couple of years, but it makes me nervous of the heating system shutting down exactly when you need it most! The York (and other A2W units) tend to go to -25C, which I am more comfortable with. 2) (and this is A2A in general) - I'm nervous of the proprietary nature of the systems. Apart from thr F-Gas issue for working on them, it doesn't seem that easy to swap/move/add individual modules (indoor units or the outdoor unit). With wet systems you can change the boiler and leave the rest of the system as is or swap out a faulty boiler with any other similar one you can grab for peanuts at any builders merchant that day. We have a lot of systems to maintain and niggles with individual parts of the heating system are fairly common. At the moment swapping bad rads or trouble shooting is easy(ish). Sure if a boiler goes we get our regular boiler engineers in, but they can put (nearly) any brand or model in. it's not like we have to use a Worcester Bosch boiler because we have WB rads! I still might go the A2A route, but I thought an investigation of A2W would be worth it. I quite like the Vaillant units, but they are a little bulkier and crucially alot more expensive - hence the queery about the York units. If they aren't mickey mouse, they would make the A2W type system alot more viable. I'll have a look at Midea, but I found that York USA seems to be associated with Johnson Controls who are big wheels in the home automation/control world. It's possible the Midea control units are Johnson ones! Edit: Had a look, I don't think they are Midea - the dimensions of the units are very different

Good point. I did a quick napkin study. Right now EON E7 is 40pkwh/14pkwh day/night Standard tariff is 30pkwh So as long as the SCOP is greater than 2 (which should be doable) the tenant will end up ahead. That ignores the advantage of lower day rates for things like electric shower etc. Servicing the storage heaters doesn't really do anything. In their favour there is bugger all to go wrong. The main issue is the old one of leaking all the heat away in the day and having none at night. The only way we've found to get around this is to replace them with new ones which do, to be fair, have better insulation. But they cost £700+ each and are only marginally better. Plus the fancy electronic "predictive" system that they rely on to get better efficiency, makes them harder for tenants to understand and use so we get lots of "call backs" to sort out. I also worry there is more to go wrong.

It's not a prepaid meter, but i suspect there is some sort of FUBAR with the billing and EON are asking way too much.

Has anyone got any experience with York Heatpumps? BRS seem to a be a UK partner for York, who seem to be a large US aircon manufacturer https://brsheatpumps.co.uk/products/ Their monoblock range seem very compact and also very competitively priced. What's the catch? Is there a catch? I'm looking to start refitting some flats I manage that are currently using storage heaters. The tenants are complaining it's costing them a fortune (£100 a week!). I'm limited in what I can do on the fabric side for various reasons. It seems that using a heat pump would be an obvious win, even if the efficiency isn't spectacular, it would still be cheaper than storage heaters. I am considering an A2A multisplit. My one concern is the systems are tightly integrated. You are tied to a certain manufacturer for parts and servicing for the entire system. You could end up needing to replace the entire system because you can't get a part for a single unit. With a wet system the emitters are more of a commodity, and the various parts can be more "mixed and matched". But the cost of wet systems is really high and the outdoor units tend to be huge. Hence the interest in the York.
