Heating without gas, it can be done with a heat pump!

How do you heat your House? Chances are you have a central heating boiler, powered by gas. If you’re in Scotland and off grid, this could even be oil. But did you know that it can be done with a heat pump? In Germany and Scandinavia they already use a lot of heat pumps in homes, while we here in Scottland we should be ar the forefront with the technique. Heating your home with a heat pump, what does that mean?

Heating without gas, it can be done with a heat pump!


The well-known central heating boiler

Central heating does actually means nothing more than that central heat is generated. the water in the boiler is heated and that is usually done by the burning of gas. The hot water is circulated so that the heat  can be emited through the radiators in the House.

The working of a heat pump differs from that of a central heating boiler.

Just like the central heating boiler, a heat pump generates the heating. You can also combine it with a boiler for hot water supply. The big difference is that a heat pump does not consume fuel (the pump itself runs on electric current). So you don’t need gas, nor do you need the supply of air for the combustion and there are no flue gases. The heat pump will extract heat from the outside.

Natural heat sources

Heat from the outside, in our cold and damp country? Yes! A heat pump will extract heat from a natural source, such as the soil, the groundwater or just the outside air. This is possible because a heat pump needs very little heat. And since you need no fossil fuel for combustion, the use of such a natural source is sustainable and environmentally friendly. With a heat pump can heat your entire house.

Pick up a few degrees of heat

An example of a natural heat source around the home is for instance a vertical ground source heat pump. To do this, leave you drill one or more wells to a certain depth, depending on your energy demand and soil conditions. Through a closed system a liquid mixture is pumped that extracts geothermal energy from the ground. Because heat is picked up, it is also called the heat collector. A few degrees is sufficient already, the heat pump does the rest.

The working of a heat pump

Heat pumps take heat from a lower temperature to release that heat again at a higher temperature. Most heat pumps use the principle that a liquid can turn into gas and back again in liquid form. You can compare it to the coolant in your car. Or you can compare it with your refrigerator, which does the same thing, but then in reverse order. A refrigerator brings warmth from the inside out, a heat pump will extract heat from the outside to the inside.

Pleasantly warm in 3 steps:

A complete heat pump system consists of 3 different parts:

  1. Part 1: heat from the source: Heat is extracted from a natural source, as in this example, geothermal energy from the ground. The source is connected to the heat pump and the earth’s heat is transmitted to the pump.
  2. Part 2: heat transfer in the pump: The heart of the heat pump is a closed loop in which refrigerant runs. This liquid evaporates to gas and condenses to liquid under the influence of temperature and pressure. This releases energy in the form of heat.
  3. Part 3: emission of heat using the heating system: The heat pump gives the extra heat to the underfloor heating system which then emits the heat in the house.

When do you choose a heat pump?

A heat pump delivers the most energy when the temperature of the outside heat source is not too different from the heatting systtem inside the house. You can best combine a heat pump with a low temperature heating system, such as underfloor heating. Because the surface is very large, you can do with a lower temperature. The water in a radiator is much warmer. New build homes have the advantage that you can take into account the installation of the source, the heat pump and the heating system. In any case, it is important that your house is well insulated, otherwise you need extra resources and that makes it expensive. here is also a subsidy available for heat pumps.  

Comfortable living

How much power you need depends amongst other things, on your home: how good is the insulation, what is the size of your property? Do you want the heat pump only to heat the house or also supply hot tap water? And of course it depends on the environment which source is most suitable in your situation. The energy output of a heat pump is expressed in ‘Coefficient of Performance’: the COP value and that value is always more than sufficient. The craftsman will calculate it all for you accurately.
