Winterwarm HR: a smart investment
In comparison with traditonial unit air heaters the energy consumption can be reduced by as much as 30% ! The investement payback period of the higher purchase price is only 2,7 years beacuase of the energy savings!
Calculation example HR 40:
Gas consumption TR 40 : 4,6 m3/hr
Number of running hours per year : 1000 hrs
Gas consumption costs per year,
at a rate of £ 0.50/kw/hr : appr. £ 2300
Efficiency HR 40 : 106%
Efficiency TR 40 : 91.7%
Energy savings per year : 14.3% x £ 2300 = £ 329
Buying price HR 40 : £ 2913
Buying price TR 40 : £ 2017
£ 896
The HR heater investment payback period on the above example is only £ 896/329 = 2.7 year!
