Emergency boiler repair – an opportunity in disguise!

An emergency boiler repair is a great opportunity to revise the entire system and even opt for a durable low temperature heating system.

Any heating professional knows that for a heating system to run efficiently it must be considered as a whole. Only when the individual components that generate, distribute and emit heat are fully co-ordinated, can the heating system function properly. So when a new boiler is installed, the heat emitters should be reviewed also. Radiators are still the most commonly used heat emitters, and new radiators make the perfect renovation duo with a new boiler for the optimal functioning of the heating system.

*Save up to 30% with Low Temperature Heating

Low temperature heating can be achieved with various heat sources. Appropriately designed low temperature hot water systems work efficiently with condensing boilers, and the heating system is already prepared for when the property might in future be updated to a fully renewable heat source, eg heat pump. Find out how low temperature heating can help save up to 30% energy.

How to reduce your HVAC system’s carbon footprint

In the EU, buildings are responsible for 40% of the total energy consumption and 36% of greenhouse gas emissions. Given that about 50% of that energy consumption is related to the HVAC system, the heating and cooling system offers a great opportunity to reduce our carbon footprint, and is a key factor in obtaining our Net Zero carbon emissions target by 2050.

Boosting energy efficiency: how low temperature heating can help save up to 30% energy

In an effort to make our buildings more energy efficient, many people are switching to low temperature heating. In older buildings this often involves the installation of a new boiler, which in turn entails the replacement of most of the radiators. The decision to renovate the heating system therefore implies a certain cost, but this will no doubt be recouped in the long run due to the reduced energy consumption, which, according to our study, can be as high as 30%. Naturally, the exact savings potential must be calculated individually since every property is different and general recommendations can only serve as a guideline. It is a fact, however, that modern heating technology only delivers its maximum potential when heat generators, heat emitters and control technology are optimally matched.
