HEAT PUMP PRODUCTS SUMMARY

A) >85⁰C TWO-STAGE HEAT PUMP;

This heat pump is essential to convert old boiler as the older LPHW systems are design for 70/90C conditions so we can plug & play these heat pumps to older properties. This heat pump is a two stage (i.e., two compressors running together in cascade format) although this concept is nearly 30~40% higher in cost than single compressor version but if offers down to -35⁰C operation, far less defrost as second stage never defrost and half of the first stage defrost, rapid response and may eliminate the need for a buffer vessel.

B) >70C SINGLE STAGE HEAT PUMP;

New condensing boilers tend to operate around 70⁰C levels as that is the optimum so if we are going to replace these systems 70⁰C heat pump would be ideal and we have these new heat pumps looks like exactly like all others but provides 70⁰C water supply as opposed to conventional 55~60⁰C units.

C) >60⁰C HEAT PUMP WITH BUILT-IN TANK;

Any conventional installation using 55~60⁰C water supply and requiring a buffer tank this heat pump complete with internal buffer tank eliminates internal hot water tank + heat pump buffer requirements. Again, the idea stays outside the house and as little disruption as possible internally.

D) 50~60⁰C  CONVENTIONAL LOW TEMPERATURE HEAT PUMPs;

These are standard single stage heat pumps for both heating and cooling options.

E) R744 (CO₂) HEAT PUMPS;

CO₂ heat pumps offer environmentally friendly refrigerant options with relatively high temperature water supply.

F) >120⁰C INDUSTRIAL HEAT PUMPS / STEAM GENERATORS;

Utilising the benefit of CO₂ heat pumps one can produce temperature for water vapour at 125⁰C and in fact using special heat exchanger these industrial CO₂ heat pumps can produce as high as 160⁰C water vapour in order replace the industrial boilers.

G) HEAT PUMPS AUXILIARY SYSTEMS; 

Heat pumps with fan coil units offer both cooling and heating capabilities without extra costs. These units provide higher efficiency and quick response, making them a valuable addition to any heat pump installation.
