THRs C Boiler No Case

Versatile Boiler Range

Ideal for installations that incorporate two heating circuits at different temperatures, such as underfloor heating and radiators or underfloor heating and towel rails.

THRs

Pre-mix, Gas Fired, Condensing Boilers - for Domestic and light Commercial Applications

The Evinox THRs range of high efficiency boilers features models with outputs to suit a variety of applications, from studio flat’s to large modern homes or small commercial premises. The range includes system boilers and double circuit boilers.

THRs system boilers provide the opportunity to work as heating or hot water only models or as heating and hot water models by the insertion of our integral diverter valve. The integral valve provides dual modulation so full boiler power is applied when heating the hot water and full linear modulation is applied to the heating circuit. The combination of a THRs boiler and EBS hot water tank provides vast amounts of hot water from a small store.

The hot water performance and heating load matched to each individual property by full linear modulation of the heating circuit sets us apart as world leaders in performance and technology. The oversized fin tubed heat exchanger and its combustion chamber cooled by water in the upper section, combines the function of heat exchanger and condenser all in one purpose designed unit. The operation of our dual modulation ensures that we always have full boiler power available when recovering the hot water and full linear modulation for the heating circuit.

For example, in the case of our THRs 5-25 C model, on hot water demand, the boiler runs at max 25kW for fast recovery hot water and then varies the heating output between 5 and 25kW to match the heating demand. With the modern home now becoming more efficient, the heating requirement is being reduced with increased levels of insulation. However, the hot water requirement is increasing with high pressure showers and bathrooms are now not just a necessity but also places of relaxation and pleasure. The dual modulation of the THRs matched to an EBS tank meets every demand by matching its boiler power output at all times.

For the heating circuit, the THRs varies its boiler output to suit changes in weather conditions. This means that the boiler, to perfectly match the heat required by the home at any given time, supplies only the minimum amount of heat to meet demand, thus ensuring high levels of home comfort and efficiency are always achieved.

Features

  • All boilers are class 5 NOx rated
  • In-built weather compensation as standard
  • Unique low output boilers with 0.9-9kW and 2-17kW modulation range
  • 10-year warranty on stainless steel 316L heat exchanger
  • Double circuit models
  • System boilers
  • Multiple zone and multiple boiler controls
  • Wide range of flue options including the unique cascade flue system
  • Efficiency up to 109.3%

Weather Compensation and Frost Protection

An outside temperature sensor is supplied as standard with the THRs boiler to enable the heating circuit to compensate for weather changes and protect against frost damage to the system. Our user friendly control kit wires back to the boiler microprocessor to simplify installation.

All THRs boilers can be installed with our unique cascade flue system, which connects to a central flue riser within the building. The unique vertical cascade flue system enables the connection of 11 boilers over 11 storeys on a common 110mm flue riser with the boilers remaining room sealed.
