Hello,
we are planning a two-family house with 240 sqm and have the following choice regarding the heating system:
-Standard Brötje – heat pump system complete package consisting of:
air-water heat pump Split-K, up to 10.9KW with 220l integrated
hot water storage, electric heating rod, 100l buffer storage and
commissioning by factory service
Heating capacity at A7/W35 (kW) 10.9
COP at A7/W35 4.2
Electric power consumption at A7/W35 (kW) 2.57
COP according to BAFA list
A-7 / W35 2.46
A2 / W35 3.10
A10 / W35 4.45
Sound level inside 52 db outside 65 db
- Heat pump Dimplex System M Comfort 12 KW water storage 220 l
for 950 € extra cost
Energy efficiency class low temperature A++
Energy efficiency class high temperature A+
Energy efficiency class hot water preparation / draw-off cycle A / L
Heating water flow temperature 60 °C +/–2 °C
Operating range air (heating mode) –22 °C to +35 °C
Heating water flow / free pressure 1.9 m³/h / 18000 Pa
Dimensions indoor unit (W x H x D) 600 x 1400 x 750 mm
Dimensions outdoor unit (W x H x D) 850 x 1230 x 600 mm
Weight indoor unit / outdoor unit 171 kg / 98 kg
Sound power level outside (normal operation/reduced) 55 dB(A) / 54 dB(A)
Sound power level inside 45 dB(A)
Sound pressure level inside at 1 m 34 dB(A)
Connection voltage (load voltage heat pump) / fuse 3/N/PE ~ 400 V (50 Hz) / C 13 A
Connection voltage (control voltage) 1/N/PE ~ 230 V (50 Hz)
Heating capacity A7/W35 / COP 11.0 kW / 4.7
Heating capacity A2/W35 / COP 8.6 kW / 3.8
Heating capacity A-7/W35 / COP 7.0 kW / 2.9
COP according to BAFA list:
A-7 / W35 2.87
A2 / W35 3.77
A10 / W35 5.03
(Smart Grid Ready)
- Gas condensing boiler system Weishaupt Thermo Condens WTC 15 AH-PEA complete package with gas condensing unit WTC-15A. Hydraulic set, mixing group NW 25, expansion vessel 105l, cap valve, switching valve, exhaust system. Solar system package F2 8550/15 consisting of energy storage WES 910 A C, 5 x flat collector K 6 gross area 12.55 sqm, rooftop installation, flexible pipe, pump group, solar controller, installation set hot water with solar system for hot water and heating support
extra cost 3600 € + cost for gas connection
We are leaning towards the Dimplex heat pump because it has better values than the Brötje and gas requires too high additional costs.
However, there is a 1500 € subsidy for the Brötje because it is power-regulated.
For the Dimplex only 1300 € (fixed speed).
What is better?
Am I right with my assessment or how would you evaluate it?
