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…

All electric property with air source heat pump
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…

Going from Coal to Air Heat Source Pump and PV's using ECO4 grant scheme
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.…

High KW Air Source Heat Pump options
Hi, I've a largeish renovated property (320sqm) which is well insulated, has wet underfloor heating down stairs and radiators upstairs. It has an Oil boilder at present. I've had ASHP suppliers around who look nervous suggesting stardard ASHP at around the 12kw to 16kw or suggesting hybrid systems that keep the oil boiler…

New ASHP and HIVE app.
We have our new ASHP in, being commissioned tomorrow. The Heating Engineer handed me a HIVE HUB today, if I want to use it. I’m very keen as I love technology and previously had a NEST with our oil central heating. So, I’m trying to register an account with HIVE ready for when it’s all working. But I have fallen at the…

Grunfos central heating pump
Pump stuck after being left off. Stripped it down then cleaned and eased the seized impeller so thought all was a goer. However, on switching on - nothing. What can cause this? Any suggestions? Does it have a capacitor or internal fuse. I checked windings for continuity and all seemed ok. Baffling.

Buying oil heated house - check suitability for heat pump
Hi, we've had an offer accepted on a property that has an oil heating system. Our offer considered the cost of installing a heat pump should the oil system need replacing after 2025 (it has been recently refurbed). In discussion with a friend it was mentioned that not all houses are suitable and there could be some cost…

Heating not coming on with air source heat pump
Hi all, looking for some advice. We have just had a Grant Heat Pump installed. The only issue we have is the heating is not coming on as scheduled. The water cycle takes precedence, of course, but even when there is not hot water demand the heating will not kick in. The only way we can get the heating on is to either turn…
