Air to air heat pump?
Hello everyone. I’m in the process of renovating a 1950s 3 bed semi, and my priorities are insulation and heating. The current heating system is old storage heaters, and immersion for hot water. I’ve been researching different heating systems for a while now, and would appreciate any input to help in my decision. I’ve…

Is Valliant extended warranty worth it?
https://www.vaillant.co.uk/service/heat-pump-cover-care-packages/ I noticed the extended warranty includes annual service. Or is it better to just buy a third party service plan which is about £220 a year.

DIY & Ecodan Heating System
I've just moved into a house with an Ecodan Heating System, I know nothing about ASHP so this is quite a step learning curve. It was installed by GreenGen in 2021 and I've booked a service and hope they can explain a bit to me then. Unfortunately the service is not until March and I wanted to remove a handbasin and…

Under Floor Heating with my GSHP
Hi all, Happy New Year. I have a problem with my underfloor heating, unfortunately I suspect it could be a messy fix. When it was installed in 2009/10, one of the plumbers kink'd the pipe to one of my upstairs bathrooms. The pipe runs in spreader plates fixed between joists with insulation fixed below. Instead of cutting…

My ASHP Journey in Bonnie Scotland.
We have our new ASHP - just three weeks now and I want to get the best from it. As it was part funded by a renewables grant we also had a phenomenal amount of additional insulation put in the attic. We have 2 zones - upstairs and downstairs. I have so far left the settings as put by the installer. 20 downstairs 18…

Frozen Heat Pump
Our first winter with a heat pump and it is very cold here (around minus 10 last night). The back of the pump has frozen over: One side has rather a thick covering of ice. Is this normal? Online reading suggests it should run a defrost and low refrigerant could be an issue? It's a 12kw 6th Gen Samsung. Thank you in advance…

Powerflush with GSHP
We had a slow leak on our central heating for a while, which suddenly became a fast leak (about 1 bar every 10 hours). Can't find evidence of a leak anywhere. I called a leak detection company. They advised a power flush because leak sealant has previously been added to the system, which can interfere with leak detection…

Extra heat sources impact on HP
I have an A2A HP and a log burner in my lounge. I am having a wet HP system fitted, what will be the impact of using the first two on the third? As an example, I light the log burner at night and the room temp (door closed) might hit high twenty c’s, how will that impact on the rest of the house?

Completely new to heat pumps
Hi everyone I am completely new to all of this - but we are looking to purchase a property that already has central heating via an air source heat pump. I know absolutely nothing about how this sort of system works and how it could compare in cost to what we have now. Currently we have multi fuel heating, with all of our…

Complex Leak in system after Heat Pump Install
Hi, I thought I would look here to get some information, as I seem to be going round in circles with Octopus. Last December I had a Daikin heat pump installed through Octopus, it was a painful process to get that far but I was excited when it went in. Since then though it's really not been smooth sailing. I noticed almost…

Thinking of buying a house with an ashp, thermal store and hw solar panels, what do I need to as
We are looking at buying a house, built 2020, EPC rating B, that has a Grant Aerona 3 ashp, thermal store, UFH, traditional radiators, and solar panels for hot water. It has propane gas cylinders for one gas hob, and also a wood burner. I’ve read about ashp, and have a basic understanding of how they work, but don’t know…

Does the MyVaillant app allow you to control Room Temp Modulation?
The Vaillant SensoComfort allows you to set Room Temperature Modulation to either Inactive, Active or Expanded. However I cannot find an equivalent feature on the MyVaillant app. Is this feature not there, or have I been simply looking in the wrong place?

Microbore Pipes
We've got 10mm "microbore" pipes and had an Octopus surveyor come round. He stated that they could deal with this challenge and we accepted the quote. Then "computer says NO." I complained about this and the explanation is to do with flow. The heat pumps they use need a higher flow rate and therefore larger diameter pipes.…

Power Cut - Heat Pump Evaporator Iced Up
We had a power cut last night and 1 hour later power was restored. The heat pump was iced prior to the power going out. Once power was restored the unit powered up again and after 30 minutes I became nervous that the evaporator was at -20C, fully iced up, hardly any air flow across the evaporator, so I have shut it down.…

Stopping payment of gas standing charge

I don't understand how temperature is regulated with my ASHP
I have a Vaillant aroTherm Plus 5kW heat pump and a SensoComfort 720f thermostatic controller. The SensoComfort has a control called a heat curve which determines my system's flow temperature for any given outside temperature. But there is also a control to set the desired ambient temperature. What I don't understand is…

How to operate heating without room sensor/thermostat/controller thingie
Afternoon all I have an Ecodan heat pump and a Mitsubishi portable wireless remote controller. A couple of days ago I managed to drop it and the batteries came out. Having done lots of reading and tried various things I'm pretty sure I need to re-pair it with the receiver and I'm fairly clear how to do this. However the…

Help needed please - just moved and can't figure out the heating/hot water
As title... we've just moved to a bungalow which has an ASHP and underfloor heating. It was reasonably mild when we moved but has turned chillier in the last few days and we've been trying to figure out how it all works. No manuals or instructions were left and we haven't elicited any useful information from Google,…
