"So use that same thermometer to measure the temperature where it leaves the heat pump outside. " I'll get to that later today Dave and advise.

Well insulated Peter is the black neoprene 20 mm taped joins and no gaps. The pipe run from the HP to the wall is 800 and I'm measuring just inside the wall. Isolating cocks are wide open so no restriction in flow there. I just wondered if anyone else had a similar experience with the Samsung.

Yes as far as I know Dave. They spent a long time under the floor 3 hours getting everything set up and clearing the air out of the system. I have asked them to come back, but because of the virus its not going to be soon. Its the drop in temperature thats puzzling. I'm measuring just inside the wall on the flow pipe, before any mixer etc, and its about an 8 degree drop, consistently, which makes me think the HP isn't achieving even the 44c that it says it is.

No Dave, Different thermometers but all read the same, within 1c of each other. ( apart from the integral one in the HP which I can't get to to test) The HP is only getting to 43-44c at -1.. according to the manual it sould be capable of getting to 50c.

What would you like to know? UFH via gas initially in the kitchen extension installed in 2007 and UFH pipes running between joists in the suspended ground floor with a multi layer fopil insulation stapled in below. 2018 My brother and I renovated the ground floor, reorgainmed the sitting room, bathroom and doenstairs bedroom making better use of the space and installing a wetroom with decent bath. we installed new engineered flooring so we buried the pipes in sand which works well but doesn't have the response time that the old system had. 2019 first floor extension 2 large dormers and a porch with heat recovery installed but unfortunately got a bad builder..who promised stairs and doors that never turned and as we discovered recently, didn't tile the roof with enough cover. So since October, we've been doing what we can with whoever we can find to fix the problems. Still about 2-3 weeks work away from finishing the job but with the virus, I think this might be about 5 or 6 months.

Hi, We've had a Samsung 9kw ASHP air to water, since September but it has never reached its supposed max temperature. We're living in a house thats not quite finished on the outside and has a load of draughts when its windy so loosing heat in the roof area. The ground floor is underfloor heated, 1st floor is radiators. The heatpump is supposed to reach about 50c heating waterflow at minus temperatures but it only ever gets to 43-44c at the pump. By the time it has got inside the wall.. about 1m away from the pump this flow has dropped to 35c and remailns at that temp to the manifolds 3m later.. the return on the manifolds is at 30c. I have calibrated the thermometers/sensors on the inside and they are all within 1 degree c of each other. 3 weeks ago the installers came and replaced the PCB and checked over the ASHP but this has made no difference. I'm wondering if there might be a problem with the internal thermostat in the ASHP? Has anyone else seen this problem?

Hi, We're renovating a 1966 semi in Aberdeenshire upgraging insulation and installing "green" technology. We've achieved an A 99 rating from D 64. Currently 40 tube solar themal heating 300l water 5.6kw solar PV capped at 4kw supplying 4.4kw saltwater batteries, awaiting connection to 11kw. Running a Tesla Model 3 and a Samsung ASHP. Awaiting connection of our smart meter to take advantage of the Octopus Agile tariff. Also awaiting the tiles going on the dormer extension so the A99 doen't quite work at the moment.
