Termal combi boiler: Choosing a Model Based on Power and Heating System

When buying a Termal combi boiler, choosing the device's power according to the home's heating system is one of the most important issues. The availability of Termal models with different power ratings on the market creates options for different needs, from small apartments to larger living spaces.

When choosing a combi boiler, instead of just prioritizing a high kW rating, it is more appropriate to consider the home's heat loss, the total power of the radiators, and hot water usage together.

How to choose between Termal combi boilers of 24, 28, 32, 40, and 50 kW?

It is possible to find various power options in Termal combi boilers. A low-power model may be sufficient for a smaller heating system, while as the number of radiators and heating load increase, a higher power may be needed.

However, it is not correct to choose the power of the combi boiler based only on the square footage of the house. Ceiling height, insulation, windows, and radiator sizes should also be included in the calculation.

Why is a dual-circuit Termal combi boiler model used?

A dual-circuit combi boiler provides both heating for radiators and preparation of hot water for domestic use within a single system.

When choosing such a model, it is necessary to pay attention not only to the heating power but also to hot water usage. If the demand for hot water in the bathroom and kitchen is high, it is important that the device can handle this load.

Why does the price of a Termal combi boiler vary according to power?

The price of a Termal combi boiler can vary depending on the device's power, technical structure, and model features. Since combi boilers with higher kW ratings are designed to handle larger heating loads, price differences may arise.

When choosing, it is more correct to look at what power is actually needed for the house, not just the purchase price. Buying a model with higher power than needed does not always create an advantage.

Why is the volume of the expansion tank important for a Termal combi boiler?

As the heating system heats up, the volume of water in the system increases. The expansion tank helps manage the additional pressure created during this change.

When the number of radiators and the amount of water in the system are high, the suitability of the expansion tank becomes more important. When choosing a combi boiler for a large heating system, it is useful to check this indicator among the technical specifications.

How should the volume of the heating system be considered when buying a Termal combi boiler?

In a large house, not only the square footage but also the number and size of the radiators determine the heating load that the combi boiler must meet.

For example, if one of two houses with the same area has more and larger radiators, the water volume and heating demand of the system may be different. Therefore, it is a more correct approach to choose the combi boiler according to the existing heating system.
