Nibe F2015 Air Sourced Heat Pump..... Chances of selling second hand?

[Dave2360]

Hello All

Forgive me if this the wrong forum for this question, but i could really do with some direction from the experts!

I have recently moved into a new Millgate Homes house that came complete with a Nibe F2015 ASHP for all heating requirements (ex Hot Water for taps). The house also included an Energy Monitor and as you can possibly guess we seemed to be using a lot of electricity and accumulating a hefty power bill.. on the last check it was £490 for a seven week period, or £10 a day average.

We had no warning of the high costs associated to the ASHP and when escalated to the MD of Millgate Homes he accepted that they are not the best option for an area with Gas Supply due to the high running costs. In fact, he stated that they have installed 20 over the past 3 years to meet the local councils directives around renewables and in that period 18 have been decommissioned, I guess leaving only me and another soon to be shocked Millgate customer with them running..

When asked why i was not informed of the highcosts, he replied, 'your a business man' what would you have done... got to admire his transparency.

Anyhow, enough moaning. Millgate have offered to cover the cost of removing the ASHP, but on the agreement that they keep all the associated kit - F2015 + Buffer Tank + SMO 05 etc... In my mind not a good deal given the RRP of this kit and the fact its only 5-6 months old. Alternatively, they suggest that I pay for the system to be removed and then sell second hand to cover costs..

My plumber seems to think I will be able to sell second hand, but i have not seen and second hand/refurbished systems on ebay etc, so is anyone likely to buy??

Can anyone provide any guidance on reselling such a system? I have spoken to a number of Nibe premier fitters listed on nibe.com and whilst they have been really useful in terms of how best to run the system, none have been interested in buying.

Hopefully you can offer guidance and i have not offended anyone with a sales question!

Many Thanks

Dave

Our biggest problem was exactly what you have said, plumbers not knowing what they were doing from the main contractor down to their two subcontractors but the actual pipe work isn't bad at all that is if you forgive them for installing the two houses with the same pipe work they bent for one!!! The sub contractor that professed to be heat pump engineers made a fortune installing this sort of technology to the council, a fortune.
So anyway we ended up, passed by our ex council's building control officer, with the system plumbed back to front, our tundish is around the back of the tank as is one of the immersion heaters, which if ever needs replacing will have to be done by a midget contortionist trained as a plumber, we have been told that correcting the plumbers work would be as costly as installing the system.
But with the house now properly insulated and drafts kept to the minimum the system now works well and brings the house up to 20 degrees quite fast.

PROPERLY designed and installed systems cause no problems - we have loads of more than satisfied customers. We design in Worcestershire for -5°C outdoors and appropriate flow temperatures depending upon emitter type and design. When sized correctly, radiators can run at 45°C flow - we do it all the time with no problems. We have heat pumps that can happily go down to -20° at full outuput.

Not only that we design OUT the immersion heater backup systems, indeed the MCS standard doesn't allow you to consider the immersion backup in normal operation.

Choosing the right type of heat pump for the designed environment is critical. Manufacturers quote A7/W35 as a default because that is the EU standard, performance figures for designed outdoor temp and flow temp are all available.

Some heatpumps (checkout C02 heatpumps) are more than capable of providing 60° at high SCoP's

99%+ of plumbers and gas/oil engineers don't have a clue how to install or configure a heat pump system.

I quite agree. And with the system in question (and also with a couple of wood pellet systems some years ago with a different supplier) we went to supposed 'experts'. In the case of the ASHP it was inconvenient as at the end of the day the main contractor ended up with less spare capacity on the substation, however with the pellet systems the saga dragged on for nearly five years and cost a bundle.
