Yes saw the Solar plates that claim to cut install time of 4kW system to 4 hours. It is a new build house (August). We have ashp and we are kicking ourselves having not asked them to put solar panels on when building. We want to be environment but not at all cost. The 3 phase costs £150, maybe due to different inverter? He also said can’t have battery. He’s coming for site visit next week.

Anyone had this done? The company we contacted said was more complicated to install equating to £1000 additional install cost. Also costs more as we have 3 phase electricity. Just looking for experiences. Thanks

Reading up whether solar PV is a good investment, seems there is a payback period of at least 15 years. What I am unsure of is do those calculations take into account running a heat pump? I guess the time they are generating most output is when you are using least electricity. If it could heat the water in summer you could use more of the produced energy, have read about diverters. Has anyone got experience of retrofitting to existing system? We have ecodan packaged cylinder running 14kw ecodan ho with ufh throughout

No gas in the village. Average is 500kwh a month. Dhw seems to be main driver for consumption. Thought about solar thermal panels but doesn’t seem to be cost effective & doesn’t provide much in winter. Hoping levies will be reduced on electricity over the next decade

Our weather compensation curve

This is what the boost circulation is connected to. Pump I’m guessing?!

Seems a lot not that we spend that amount of time!

Flow rate at 3 bar pressure 24 l/min according to the spec of shower head

I’ll have a look! no, just the one halfway down

I don’t think water is being circulated unless hit the boost on the premise it’ll sit in the pipes cooling which is a waste. Or will this not happen as much as the slab is up to temperature? Keen to understand as much as possible before cold weather hits!

It’s a rain shower but we don’t spend that long in there. numpty question but how do I know the ufh loop is open?

So does that suggest that only half the tank is up to temp?

Me too! It drops a degree every couple hours otherwise. I assumed it was filling up tank with cold water when the hot was consumed so was mixing. I think the temp probe is midway down tank so figured there is warmer water at the top

If we click on boost on this it send hot water to the taps

Hi all, thanks for taking time to reply! From EPC floor area is 278 square meters is 89B energy rated. Walls 0.15 ave thermal transmittance, Roof 0.11 and Floor 0.13. Windows high performance glazing Its ufh heating throughout and hot water tank is 300l. It heats up to 48 degrees, save once a week legionella cycle. It drops significantly after a shower, to about 24 but if the boost is used then second shower is definitely warmer than that. To provide above water uses about 3kwh. No buffer tank and don’t think immersion is being used other than the legionella cycle. No PV and no MVHR. We have a weather compensation curve set up, from what I’ve read & if am understanding it correctly it is a bit high - If it’s 10 outside the flow will be 40 degrees. sorry if missed a question in your responses, will have another read through after work ?

Hi all, we moved into a 5 bed new build home in August which is a highly insulated timber framed house with an Ecodan 14kw HP and are trying to get to grips with it. Our heating engineer installer is trained but hasn’t had a lot of experience so we are not totally convinced it is set up optimally. There are 2 of us, working from home. We currently have space heating on 6.30am-9pm as we like a quiet house while we sleep. Hot water programmed for 5.30am-6-30am and again 6.30-7.30 at night. Bedrooms set for 19 degrees, and main living areas/studies are 21. Our en-suite floor temp is 23. Each room has a heat miser stat and none of them are switched off. It is a bit of a shock not having hot water all the time but was costing a lot. We switch on the boost before having shower and have nice hot water but during the day we have cold/tepid water to wash hands. Anything you might do differently here? In this mild weather the rooms come up to temperature pretty quickly. I think we may be seeing short cycling though. Every hour when heating is on but none of the rooms are calling for power, it fires up the HP when the flow temp drops to 38 degrees and then raises it to 55 before letting it drop again. Looking at the energy monitor it uses 2kwh whilst doing it & not sure what the benefit is to it or us! If anyone has answer for that that would be great. One thing to know is the connector to call heat isn’t currently installed as we have towel rads that we’re going to be separately heated when space heating isn’t on. Doesn’t seem to get them hot so we are getting this changed. Hopefully this will fix the above behaviour. The return flow temp is often higher than the flow temp, not sure how that’s possible? Lots to learn!
