Heatrae Amptec - don't touch with a bargepole. flakey design and pcb probs which they don't admit. Technical wouldn't approve the use of my own relays to control two boilers. Had to use their badged relays at a cost of £130 which were essentially £5 worth of parts inside a plastic box.

Trianco Aztec. These are good and have done a few jobs with them now. You still have to do all the external pump/controls etc.

BTW a tip. If you have 12kw heat load, its better if you can convince the client to have two 6kw units. The supply wiring is MUCH easier (think 6kw shower) and they have backup if one unit goes down. Downside is that you need a pump control relay for the two units and have to plumb up in parallel.
 
Interesting coz Amptec is what PTS suggested :confused:

How many rads can a 12kw handle ??

Ok this is for 10 new build flats so its the lot , heating , water, bathrooms etc , ,,
Next question is hot water supply,,, they aint got room for cylinders but I don't know of an instant hot water with electric ..

when i visited the now wifes home in sweden middle of winter the heating was off

so i spent halve an hour trying to figure out where the gas came in. :confused:

yes you guessed it was a 3 phase electric job and needed repressurising :oops:
 
Dell the problem is this, if say you wanted 23kw then you would need a single phase electric supply of 100A
 
what you need is bags of dirt cheap electric.

something we dont have.

:cry:
 
Fitted one (Amptec) last year,never again.

Problems very well documented above but the worst problem was the hot water ended up fitting a small combi-cylinder in the loft to supply a wash hand basin and the kitchen sink ,shower was an electric mira.

Hot water was cr@@p utterly cr@@p.

Punter was fine but couldn't work out how to use the time clock which was a wired version of a Honeywell CM927for the hot water and heating .

She had the water on for half an hour in the morning and at night and subsequently ran out of hot water for the whole day after doing the dishes in the morning :rolleyes:

Walk away mate :cool:
 
How about air to air heat pumps.. Dearer initially but a whole lot cheaper to run and the customer can be air conditioned in the Summer too.. for water either a straight electric immersion heater or an air to water heat pump with electric back up
