What People Say About Us

‘I have worked with HSB in a number of projects over the past few years and always found their overall approach to be of the highest professional standard, their analysis to be insightful and their proposed solutions to be both creative and feasible.’ ‘HSB is very much focused on providing workable solutions.’ 1140 Heat pump with underfloor – Luke Townsend

‘This system is much better than the older heating systems, very economical; it provides very controlled heating.’ ‘I regard it as a good investment and I was very pleased with the service and efficiency of HSB.’ 1240 Combination Heat pump with underfloor - Paudie Sugrue

‘In particular HSB have provided professional advice on all renewable energies available and explained this in lay mans terms.’ – Noel O’Sullivan

Danfoss DHP-L Heat Pump

If you have a large hot water demand, Danfoss DHP-L is the perfect choice, as it is designed to be combined with a separate hot water tank. Separate tanks are available in the
range of 160, 220, 300, 500 or 1000 litres. Danfoss DHP-L is available with outputs from 6 to 16 kW (up to 25 kW incl. electric element).

Further Information

Thanks to the use of latest technologies, Danfoss DHP-L has many convenient features. The advanced scroll compressor, specially developed for heat pumps, is one of them.
The effective heat exchanger and sub-cooler that help to extract additional heat are two other examples.

Danfoss Waterheater DWH
Danfoss DWH – the advancedomestic hot water storage

The Danfoss DWH is designed to be perfectly compatible with the Danfoss DHP-L. It is very efficient, and when used with our pump it provides optimum heating and hot water comfort. The patented TWS technology provides hot water quickly at low operating costs. The Danfoss DWH is available in two sizes, 200 and 300 litres, and with a copper-lined steel or stainless steel tank.

Danfoss heat pumps together with the domestic hot water storage DWH provide a complete solution for space heating and hot water. This system is extremely reliable and will reduce your heating costs drastically.

Special features
» The same features as DHP-H, but with separate water tank
» Can reduce heating costs by more than 50 percent


Danfoss heat pumps feature scroll compressors
as standard. Scroll compressors have fewer moving parts than conventional compressors, which increase their lifetime and reduce noise levels.
Scroll Creating energy efficient and high performance heat pumps with a long lifetime requires advanced technology. Danfoss looks back on several decades’ experience in developing and manufacturing heat pumps. Our Research and Development department is in the forefront of advances.

The heart of the heat pump




Danfoss is leading technological development compressors also provide high efficiency for production of heat and hot water over 50 °C. Which means it increases both the efficiency and the lifetime of the heat pump.

Extra & Hotter Hot Water

A traditional immersion heater provides a slow heat transfer. The hot water from the pump surrounds the
immersion heater. A technology that requires twice as long time to heat a heater that is empty, compared with the TWS technology.

A TWS water heater uses a new technique where the hot water from the heat pump is led through a coil in the water to be heated. The water in the heater is also split so that some of the water reaches the correct temperature more quickly.

TWS provides more efficient heat transfer and more warm water.

Advantages with TWS

» Quicker hot water production
» Lower the costs of hot water production
» Increases efficiency
