Upstairs has a single stat on the landing, with TRV's on the rads. I have had several issues with the system since moving in,…

Air Source Heat Pump Question
Hi, We've had our Air Source Heat pump just over a year now, it's been working OK. I have heard that these have an expected lifespan of about 10 years - does this mean I would then need to reinstall a completely new system or would the old one be repairable? It seems like a lot of money to pay out (ours was around £13k)…

ASHP's and how to use them economically?

GSHP - I need help with making it as efficient as possible!
We have a GSHP for our heating and hot water. the RHI payments end this year and so we have the double whammy of no longer getting that alongside rising energy costs, and its worrying me.

GSHP - Will prices come down?
With an ASHP, that's a more easier question to answer ie: as time goes on, the cheaper they get With a GSHP, presumably the additional costs from it isn't just the heat pump but rather the planning, drilling, and any thing that you need to put in for the piping which may end up costing more if it's copper too. I imagine…

Heatpump - Replacement cost?
Say you have the necessary piping for either an ASHP or a GSHP. Say, also that the actual heat pump breaks and you need to replace it. What percentage of the overall costs are the heat pump itself, as part of the initial installation? That'd be good to know, because it means potentially knowing that you need to save up a…

Mitsubishi Ecodan ASHP - Crippling Bills due to electricity usage.

Can anyone share their experienes of retroftitting an ASHP pease? How much disruption? What order do things get done - pump outside first, then tank, radiators and so on or vice versa?

ASHP is my quote reasonable?
I’ve been looking into getting a ASHP as my boiler needs replacing anyway. I like a few things about the ASHP the hot water tank being in my old boiler cupboard and the unit outside is ideal - I don’t have room to have a boiler and a tank indoors as all space is taken. I want a tank due to constant change in water pressure…

Amount of space required for airsource heatpump
We are about to start a large project which will include replacing our ancient gas boiler with a modern gas boiler which will be going into a full floor to ceiling height cupboard in a first floor bedroom. We are conscious that at some point in the future we may have to go down the ASHP front, so we are planning on having…

How to reduce the noise from the cylinder of an ASHP system?
I recently had an ASHP system installed in my bungalow, with the main cylinder located in a cupboard in my spare bedroom. I hadn't appreciated how loud the whirring would be and am wondering how best to reduce the noise. It's tricky to identify exactly where the noise is coming from, but it's somewhere in the orange circle…

ASHP and microbore CH pipes
I'm looking to install an ASHP at my home. All downstairs radiators run on 8mm microbore pipes fed from upstairs, where all the radiator pipes are on 15mm pipes. I'm worried I will not have a good enough flow rate downstairs to heat it at a lowish flow temperature. I don't want to run the CH at 50 degrees as my COP will be…

ASHP to heat water for a shower or electric shower?
Hi, My hot water needs are very low, at most, it's a bit for washing up and then a shower for one or two people per day. I have an Air Source Heap Pump for my heating and for hot water, although I'm not using the hot water tank at the moment. For showers, I'm just using an electric shower. What is likely to be cheaper;…

ASHP and supplementary heating
Not sure whether to post this here or in energy threads. However, we are looking to have an ASHP fitted as we have woefully inadequate heating from multifuel stove and wrap around boiler at the moment. As I believe an additional source of warmth would be needed especially in the living room on cold nights we had thought to…
