Am I right in thinking that it wouldn't matter if the ashp heated hot water ifthe heating came on just after? Say dhw timed from 6-8 then the heating comes on at 11,Would the heating just drain all the heat out the cylinder? Feel like I am asking stupid questions. Just clueless.

Thank you, I do think at has been wired incorrectly. It seems the ashp doesn't get a signal when being called by the heating only. If I have the water on constant then when heating comes on so does the ashp. I cant have the water timed because if heating comes on the ashp won't heat the water. And the ashp will come on whenever the cylinder drops below the thermostat setting to heat the water. It's been quite a challenge coming into this from a oil combo boiler. ?

Yeah I think it is basic. We only have 3 thermostats in the house and nothing driving the actuators. If I need to change the flows I have to turn the red caps. As far as the ashp goes would a newer pump be a lot more efficient? I feel this one is on its last legs. Don't think it has ever been looked after properly. Finding tradesmen who have knowledge of these systems is hard. Thought I would try on here incase of any recommendations.

So I have looked at the manuel and from what i can see, the fault finding sheet says check supply to programmer. I have mains light on only.

OK so the motorised valves come on and so do the pumps. The only way I can get the ashp to come on though when water is on on the main controller. If I switch water off and put heating on the thermostats and pumps come on but no heat being produced by ashp. 3 lights on the receiver the middle one comes in when heating called just when off as I took photo. The thermostats are milux rf. Last pic is downstairs manifold and pump.

I have had to pop out but will do this when I get back ill be about 20 min. The heating and hot water controlled by the controller in the cupboard as pictured, but the heating then responds to the thermostats connected remotely. The thermostat sends a signal to a little box which then turns on the heating. I'll send pics when I check.

The grey insulation I added because the old stuff was falling apart. I'll put a pic of where the solar connects to the cylinder. I believe its at the bottom. The 2 pipes are next to each other with the solar thermostat probe just under. The controller for the solar is in a cupboard in the attic room.

Hi, yes those pipes go into the manifold for the second floor heating. I also have 2 more. One for the attic room and one for downstairs I presume. If I switch heating only on, all the floors call for heat, the pumps come on but the ashp doesn't. I don't have any test equipment.

Think it is ideal setup. Finding anyone who knows about the pump is a nightmare. The people I have spoken with have never seen the pump before and the one guy who had said only to take one out. We were left with no info on the system when we moved in so Google has been my only friend. We had a electric bill of £470 for 47 days which was a shock. Later found out the immersion was on constant which has subsequently burned out and the cylinder thermostat was on the floor.

We have ufh downstairs and upstairs, then we have 3 small rads in the top room, which never get used. I'll post pics of the cylinder and pipework. We did have a plumber call a while back and he just shook his head when he saw the cylinder set up. We are about 15 miles from the sea.

Hi, thanks for the reply. Yeah it's all or nothing. It's the unit outside. We can't set the hot water and heating separately. If we run heating only from the controller then the heating starts but the pump never comes on. But if we have dhw on constant then the heating on the pump starts. The system is about 11 years old. I'll post some pics shortly.

Hi, I am new to this forum but have been reading a lot on the forums. Lots of people know there stuff on here. We moved into our house last December which has an ideal airtherm9 ashp with ufh and solar thermal. The pump sounds like a tractor and is rusting to bits. It is set up so we can only run heating and dhw at the same time.Just don't think it's running eficiantly. We are looking to replace the unit but finding it hard to get anyone we feel knows what they are talking about. Was hoping that someonecould recommend any installers.
