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.…

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…

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.…

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…

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…

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,…

Heat Pump - KwZ usage through the roof
Hi, We moved to a newbuild in March 2021 with gas and electric provided by heat pump. Each year, we are using around 17,000 kWh, according to British Gas, and spending more than £5,500 in the process. We are a family of two (and a dog) and it's an average-sized 4-bed house. The heat pump installer insists that there is no…

A2A Heat Pump / Air Con
As with the 29/5/2025 changes I understand that it's possible to install air con / A2A heat pump without planning permission? We don't have radiators / gas at the property and air to water heat pump costs even after grant were just too high, hence I was thinking of getting A2A mostly for heating and casual 5-7 days a year…

Beko Heatpump dryer woes DHR83431W
Myself and my wife purchased one of the new heatpump tumble driers by Beko from AO online… Given that these are more energy efficient we were hoping it might save us some cash. Now two years in (out of warantee) with light usage the dryer won’t heat. I was hoping the forum may have some advice for us in our predicament. I…

Winter Holidays and Heat Pumps
I was talking to someone about getting a heat pump to replace their gas boiler. They spend several months during the winter away from home. With their current heating, it is on the frost setting, so the boiler only starts up when it is below 5 degrees and therefore costs very little. What is the situation with a heat pump?

Modulation - what is your experience?
So my (space heating only) heat pump still doesn't run full time at 4C outside temp (about 50 mins on and 10 mins off) but does at 3C to maintain 21C inside when it is outputting about 5kw. Once it does run continuously it does so at about 1.5kw so this is clearly the lowest it will go. When it starts and stops it actually…

New to Heatpumps
HI, Can anyone advise me? I'm new to Heatpumps (Just had one fitted and Solar on the roof) and currently looking to change my electricity tariff. There doesn't seem to be any comparison site for Heatpump tariffs. If I've got my numbers right it looks like EDF is the cheapest by about £30 a month. And all supplier's are…

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…

Using ASHP in an Ad Hoc Fashion?
Hi all, so like the idea of heat pumps using renewable energy but I'm struggling to see how one would fit our use case, so knowledgeable people's insight would be greatly appreciated. I know they are most efficient running to keep the house a a certain temperature, so running a lot of the time, but we have never used…
