Information

The Grundfos Save Energy calculator gives you an indication of potential savings in terms of energy costs and CO2 emissions by comparing a new high-efficiency Grundfos heating circulator pump with an old non-controlled 3-speed pump. It can be obtained by specifying the range of the area of the house to be heated or providing the old pump's power consumption (you can check the P1 value in watts on the nameplate).

Please note that savings are indicative and provided for informational purposes only. They do not constitute an exact calculation for your house, heating installation or operating conditions. You need to contact a professional plumber/installer, if you want an exact calculation of your potential savings.

Energy savings: the calculation is based on average heating operating hours, an expected load profile of the compared pumps, and the price of electricity in the region. Prices are updated once every month from⚡️Electricity prices around the world | GlobalPetrolPrices.com.

CO2 emissions: the calculation is based on the expected yearly savings in energy consumption. The total savings in kWh are then multiplied by the local grid emissions factor in kg of CO2/kWh which then gives a total CO2 emissions output in kg.

How to find your pump

If you have underfloor heating or radiators, there is at least one circulator in your home. Here are the most common places to find it:

In your technical room

Probably where you also have your washing machine. It is either visible on the piping or inside your boiler, heat pump or central heating unit.

In your basement

Likely where your washing machine is located as well. It can be either visible on the pipes or inside your boiler, heat pump, or central heating unit.

As part of your underfloor heating

Usually there is a separate circulator for your different underfloor sections in the home. Each section has its own circulator in a cabinet where the pipes are connected.

Let’s assess whether you need to replace your circulator pump

On the front of the pump, you’ll see the energy consumption either printed or shown on a display

If your circulator shows energy consumption of more than 5W, it is one of the world’s 200 million inefficient circulators that could be replaced to save energy at home. 

If you can’t find number values, it’s likely your pump runs in the outdated “fixed speed” setting with 1 or 3 modes.

The EU prohibits new sales of these pumps because they’re so inefficient – and we recommend replacing them for optimal home comfort.
