Winterwarm HR - Condensing unit air heater

A new generation condensing unit air heaters which combines the efficiency of gas fired unit air heaters with energy savings and high comfort. All Winterwarm HR heaters are already ErP-compliant for 2021!

Unique unit air heater

For the capacities 10 to 120 kW, Winterwarm has engineered a condensing unit air heater based on their succeful XR-series. The patented design of the heatexchanger and the modulating burner regulation make it possible that the Winterwarm HR 10 - HR 60 are provided with only 1 heatexchanger.

The dimensions of the single heat exchanger design make that these HR models significantly smaller and a lot lighter than any other condensing heaters currently on the market in the same capacities.

One of the other features of the HR is the attractive design of the heater. Consequently, these heaters also look very well in commercial areas as shops or showrooms. Like the XR, it is possible to install the HR 10 through HR 60 in a tilted position (unitll 60°) which can create a more downwards directed air flow.

The available capacities at this moment range from 10 to 120 kW. The whole HR-range has ECA-listing.

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!
