AirSource Heat Pump Freezing temperatures
Hi, We have a Stiebel WPL 17 Classic Heat pump installed, when the temperature gets to freezing, we find we have a drop in pressure and the heat pump stops working. The pressure has been consistent for weeks prior to that and everything working fine. This has happened three times now. Do you think this is a leak? If so why…

Heat Pump Dryers Operational Feature
I have a BEKO heat pump dryer (model B5T4923IW) that has a DELAY start feature. The delay can be unto 24 hours - I started to use this to make the most of a lower rate of electricity consumption (early hours). However, I have discovered an operational issue that has taken ages for BEKO to confirm - not documented etc. The…

Heat Pump question
Hi all, In considering a heat pump is a viable option to retain an existing oil fired system and keep existing radiators and pipework and simply have the heat pump work in tandem? I currently use logs and oil and wouldn’t want to change from this but simply see the heat pump as an add on. Thanks.

GSHP UFH side pressure rising
Hi guys, could do with some advice. I have an IVT HT PLUS E7 (seperate hwc). The ufh side is usually set at 1.5 bar. The needle does go up to around 2 bar when the heatpump is heating the dhw side. Get's really scary like tonight when it's on the legionella cycle and the water's going above 60c to 65c. I have to reduce the…

Air source heat pump installation good bad or ugly
Hi Has everyone who had an ASH installed had a good experience? Was it very disruptive? If carpets need to come up do they put them back? Do the instalers move furniture or do you have to move them? Possibly getting an installation in the new year, we have disabilities, so not very fit, and my wife suffers from stress due…

Change to ASHP with Octopus & govt. grant?
Hi, our oil boiler is coming up to 20 years old, as is the tank in the garden. I'm an Octopus customer and saw their ASHP 'quote' form and filled it in. It said "Your heat pump quote £2715.50"... and pay £500 (refundable) deposit to start things going. Bit quick for me that! :) I then had a bit of a read around bits and…

Ecodan ASHP - what the best DHW setting for a single man living on his own?
Hi, I have an EcoDan ASHP with a 240 litre cylinder. After years of having lodgers Ive finally got the house back to myself. Its always made sense to have the DHW kept at a constant temporature (55 degrees) because anyone can have a shower or do their washing up at anytime knowing there would be hot water available.…

Bivalent ASHP and oil boiler
Our oil tank is far too small for the house, and due to the position, replacement with a larger tank is likely to be impossible. Because the tank is only 1000 litres (5 bed house, approx 3000 square feet, EPC C (72) and could probably do with more loft insulation), and minimum order is 500l I have to wait until the…

Air-source heat pump problems
LG ASHP, within 7yr warranty, failed 4 months ago. Had several visits from Climate Save Renewables of Wickford, Essex and 2 visits from LG, costing us £790 in call-out fees. New parts fitted but still no heat. Now told we need another part (£690) and that the warranty is invalid as the installer has gone out of business.…

Smart Meters and Heat Pumps
I have an Air Source Heat Pump/underfloor heating system in a very well insulated modern house. However, since electricity has increased in cost I have come to realise that they are VERY inefficient in low temperatures. I am with Octopus Energy on a single tariff Analogue meter and considering changing to Economy 7. Of…

Anti-freeze mode for ecodan ashp
This is my first winter with a Mitsibushi ashp. Now that the outside temperature has dropped to 5 degrees and below at times, anti-freeze mode is kicking in quite a bit. My question is should this be reducing the temperature of my hot water cylinder? It’s a brand new cylinder (installed as part of the eco4 scheme). I seem…

Heat pumps as a landlord
The gas boiler in our rental property is still just working but having had it checked and serviced today, our engineer reckons it won't manage another year*. We're getting a quote for a replacement gas boiler, but I was wondering about a heat pump instead (this would mean no gas connection required). Am I correct in my…

Hi, My house is all electric and we have an air source heat pump. We use 7,800 kWh of electricity per annum and are currently on a tariff with peak and off peak charging. 30p per kWh peak and 6p off peak. Off peak is midnight to 5am. Our split of usage is around 80% peak and 20% off peak and we are trying to push more to…

ASHP planning the big turn on day
Posting here to our banished, never to be seen section............. In the sunny South the suggestion.is 16oC til 23rd October but with some single figure overnight lows. So our plan and one that kept usage down last year is a little blast from electric fan heaters in the kitchen for those early mornings. No more than a…

We have a choice stay as we are G rated house coal powered house or use the Government grant scheme ECO4 and go to a B rated house air heat source pump and solar powered house. Which is going to be cheaper to run the coal or the use less but more expensive electric? I am nervous changing.

Heat pump - new radiators and pipes
Just curious as have read a bit about heat pumps needing larger rads and larger pipes is this not incredibly disruptive as imagine many houses have pipes under flooring which might be tiled, or in walls which might be papered /plastered or behind tile? Is it just larger rads of existing types or are they a set type? My…

AS Heat Pump in Old Farmhouse - Radiator Size?
Hi we are on oil, no gas and our farmhouse has rubble walls and solid ground floors. I get that everyone says 'you'll need bigger radiators' but I can't get a sense of how big that means in practice. 10% bigger, 90% bigger? For context, roof insulation could be improved but probably not by much and windows are DG and doors…

ASHP grant for self build
Morning all, we have been renovating our old barn and having the ASHP fitted at the moment. I have had conflicting reports on whether we are able to make use of the ASHP grant from the government. It is a self build but it has had no other form of heating before and we will be the first occupiers since renovation

Mitsubishi Ecodan Heat Pump help needed please
Had a U8 error message on the control panel. Phoned the local heating engineers and they said we should turn the system off outside then open the panel and check the fan was rotating freely. We did this and it was rotating okay. Turned the system back on again outside but now the control panel inside the house is blank.…
