would you expect a solar panel to have any benefit at this time of year?

Hi Cathy,
Normally we would only commission the Daikin parts that we supplied and installed, but would also work alongside the UFH specialist to ensure that the heat being generated by the Heat pump is being effectively used. However we would not have hte means to check the heating efficiency.

In the event of a call out to site we would check the operation of the heat pump first and then look to see if there was something obvious preventing the UFH from working. This might be as simplistic as taking the floor temperatures in various rooms and comparing it to the room ambient temperature, this should give some indication as to whether the UFH is working.

We could check the flow and return temperatures on the individual loops at the manifold connections to also help to establish if all of the loops are getting water circulated.

If there is a major problem with the loops once you have established that the heat pump is working properly, then you would need to get a thermal image carried out on all of the room which will help to establish the actual loop temperature under the flooring.

This really ought to be taken up by your HA as there could be some costs involved, but at least the HA could then go back to the developer to seek further assistance. A lot of the recent developments are tied into a two year defects program, which obliges the developer to get things put right.

Your HA seem to be no different to many others, they have jumped onto the heat pump scheme in order to get the correct BREAM rating for the development without actually looking into the technology or understanding the way that these systems work.

I admire you for wanting to find out more about how the system works etc, it is a pity that the HA are not as diligent.

Mike:

The Housing Association over here finance the building project and then release the houses on either a part rent/part owner ship scheme or on full rental of the properties. They are supposed to accept responsibility for the common areas and other areas as well on the full rent.

Hi Hyperion.

How could/ would I know, what the heat pump settings should be? Would this be in field settings?

It is established that the 3 point valve is now working correctly (is this the same as the heat pump?) The heating is working but patchy and/or non existent in other properties.

We could check the flow and return temperatures on the individual loops at the manifold connections to also help to establish if all of the loops are getting water circulated.

I have isolated each of the loops separately, and the feed pipes do get warm (in turn)

If there is a major problem with the loops once you have established that the heat pump is working properly, then you would need to get a thermal image carried out on all of the room which will help to establish the actual loop temperature under the flooring.

Wish me luck on getting this far with the HA!

What is a BREAM rating


Thankyou for all your help! you're a star!
