We always recommend that our clients specify separate systems to do DHW and space heating. ✅

Experience has shown us that having one system to do both, results in neither being done very well

Heat pumps serving heating systems should always be looking to reduce flow temperature based on the internal and external temperature to maximise efficiency

Stored hot water should be maintained at 60degrees and so requires a flow temperature of around 65degrees ♨️

Using one system to do both will mean that the system has to ramp up from the weather compensated temperature to 65degrees every time water is drawn off making the systems inefficient

If it doesn't ramp up when water is drawn off the DHW temperature drops below 60 and you risk low DHW temperatures ❌

Because we have always run boilers at high temp, we have always used the same boiler to do both and have carried this mentality forward

Do this with a heat pump and the result
is high running costs 💷💷💷

Yes, you have to buy 2 heat pumps, but you probably have to buy a bigger one and also have to spend money on extra hydraulics , 3 port valve and BMS controls

In many applications the DHW load is very small

On this project, we supplied a
midea MARS heat pump

This model gives 35KW with 65/55 flow and return temperatures (-5 ambient)

It cost about the same as the extra cost of making the heat pump bigger and the required components and controls

This will be cheaper to run than standalone system

The unit also uses propane refrigerant making it future proof

If you would like to discuss what is the most efficient and cost effective solution for your next project, please get in contact ☎️

We have been short listed for an award at the “National Heat Pump Awards”

Our project utilised a 150kW C02 heat pump which is being used to produce instantaneous hot water for a leisure centre.

The system is helping reduce operational carbon with a market leading efficency.

The system also uses future proof refrigerant (C02/R744) which has a GWP of 1 and so has super low embodied carbon as well.

We are looking forward to the awards ceremony later on today, cross your fingers for us!!!

40% of UK carbon emissions come from heating our buildings 🏢⛪️🏙️

Using a heat pump for heating can reduce carbon emissions by 3,4,5,6 times 🌏

The new adaptation of the building regulations and the UK government's public sector decarbonisation scheme, mean that heat pumps are becoming the go to technology for heating commercial buildings.

We stock and sell commercial heat pumps and help design systems so they are efficient and effective!

What is a market leader?

Is it about who has the biggest turnover?

At ICG Heat Pumps we believe that being a market leader is about behaviour……

It’s about selling solutions we believe in…

It’s about doing what is right even when profit suffers…….

It’s about offering the advice and support that others don’t……

We recommend the right heat pump, for the project in front of us……

The most sustainable, most efficent solution available…..

We are by your side, for feasability, design, install, commissioning and most importantly if there is a problem…..

We see lots of projects, where the solution recommended is what is best for the manufacturer or supplier selling it…..

We see lots of jobs where the manufacturer, walks away and say - not our fault……

We do things differently……..

Even if it isn’t our problem, we help you get it right……

A heat pump works on the principle of transferring heat from one location to another. It consists of four main components: an evaporator, a compressor, a condenser, and an expansion valve.

1. Evaporator: The heat pump starts by absorbing heat energy from the outside air, ground, or water source through the evaporator. A refrigerant, a substance with low boiling point, circulates through the evaporator coils and evaporates as it absorbs heat.

2. Compressor: The gaseous refrigerant from the evaporator is then compressed by the compressor, increasing its temperature and pressure. Compression raises the energy level of the refrigerant, preparing it for the next stage.

3. Condenser: The hot, pressurized refrigerant is then passed through the condenser coils. Here, it releases its heat energy to the indoor space or a hot water tank. As the refrigerant cools down, it condenses back into a liquid state.

4. Expansion Valve: After the condensation, the refrigerant flows through the expansion valve, which reduces its pressure and temperature. This prepares the refrigerant to re-enter the evaporator, repeating the cycle.

By continuously circulating the refrigerant through this cycle, a heat pump can extract heat energy from the outside air and release it at a higher temperature to heat water for your heating system.

The ability to transfer heat rather than generate it makes heat pumps more energy-efficient than traditional heating systems.
