GSHP, Bypass and Buffer Vessel
Hey Guys - when my IVT HT Plus E7 was installed in 2009-10, the installer (my own plumber) added a kind of Bypass and as far as I'm aware - it's an old trick that plumbers have done for decades - left it half open. I guess this was for circulation pumps, so they're never circulating against a closed valve. I have since…

Air Source Heat Pump for Garden Room

The boiler is now 8 years old and has become very unreliable, with an internal leak now. Its also frustrating having to replace the gas bottles. We are considering…

Air source heat pump problems

ASHP question
Our Ecodan is set so that between 11pm and 5am the heating does not come on, nor the hot water. Yet almost every night something is humming away in the off hours in the vicinity of the water cylinder - anybody have any ideas what that could be? It's been happening consistently since mid-September when I changed the…

Benefits of hybrid heat pump systems
Hi all, I wanted to share my bit of knowledge and experience on hybrid heat pump systems. This is when you do not need to remove your existing gas boiler, but pass control over it to a new heat pump controller. A small heat pump is connected in parallel with the gas boiler to your existing heating piping. The controller…

If you have a new ASHP installed recently under the grant, do you have a say in what it will be installed? Including HW cylinder and possible radiators too. Does the installer just fit…

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)…

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…
