Most of the people prefer an indoor temperature of 21°C. Heating your house while you are away from home, is a complete waste of energy and money.
Yes, if you own solar panels. The timer will allow you to heat your water using the electricity generated by your panels. Otherwise, installing a timer is of little or no benefit.
A combined heat and power (CHP) system generates both electrical power and heat from a single fuel (e.g. natural gas). The system comes with a whole host of benefits. The technology was devised to serve large buildings such as hospitals. Today however, it is also available to be used in single family homes .
It costs more to install, does not suit every home, and the yield decreases when the weather is cold. However, the advantages luckily outweigh the disadvantages.
Yes, in Brussels the periodic inspection of boilers and water heaters is mandatory if they are fired by liquid fuels (fuel oil) and gas.
The calorific value of gas is the energy that is released in the form of heat when it is burned. This is used to calculate your natural gas bill.
There are many estimates out there and not all pilot lights operate in the same way. Consulting different sources, you come across stated consumption levels ranging from 60 m³ a year, all the way up to 250 m³. Let's calculate your exact consumption.

If you have a condensing boiler, it is imperative that the chimney is moisture-resistant. For unmodified chimneys, intubation is required.
To choose a new boiler, you must consider the price but also the type of fuel, the efficiency, the combustion system, the space available and the hot water requirements.
Collect evidence to show that the problem exists. If your owner still refuses to replace or repair the boiler, you should call on the justice of the peace.
When the choice of how to heat the water is sound, the expense can change from excessive to very affordable - and very ecological...

Geothermal energy can be an excellent option for more sustainable heating in the city, provided you have the required budget and sufficient outdoor space.
For economic and environmental reasons, gradually switching from natural gas heating to renewable sources makes sense! The process is simple.
Cogeneration is a system that generates both electricity and heat from a single fuel (natural gas).
A heating audit is a test carried out as part of the regulations on the energy performance of buildings (EPB). This audit is mandatory for central heating boilers over 15 years old and has to be carried out by an approved specialist.
