Weather compensation

With ever increasing fuel bills and the need to be as eco-friendly as possible, it's important that we all look for ways to save fuel and carbon emissions - and money! With our range of our energy efficient heating systems, you will be able to do exactly this.

All gas boilers now have to be condensing boilers and this represents a huge step forward in environmentally friendly heating, with fuel savings of up to 35% compared to conventional boilers.

But there is a way to save even more - up to 15% in fact, with just a simple outdoor sensor and some very clever Weather Compensation controls, available with our Vitodens range of
condensing boilers.

For a relatively small investment, you'll not only save up to 15% more fuel each year but you'll also enjoy an incredibly comfortable home with a pleasant indoor temperature - whatever the weather.

Hydraulic balancing

The energy efficiency of a heating system can be increased by up to 15 percent – therefore, hydraulic balancing is one of the most efficient methods of reducing heating costs and CO2 in the long term.
 

Reduce heating costs with our professional saving tips

Easy and inexpensive ways to reduce your heating bills with an energy efficient heating system.

Venting the heating system

If your heating system starts "gurgling" it means the heat is not evenly distributed in the radiator; the water is no longer circulating properly. The radiator needs to be bled.

Airtight joints on windows and doors

Airtight joints on windows and doors are indispensable for economical heating. Check the seals before the heating season and replace them if required.

Insulating heating pipes even in heated rooms

Insulating heating pipes is easy. You can save money without too much effort and at minimal cost.

Use thermostatic valves for radiators

Check the function of thermostats regularly. The heating output will be reduced if the thermostat is sluggish or stuck.

More economical heating = lower heating bills

With our energy efficient heating systems, if you lower your room temperature by 1 °C, it can reduce your heating bills by around 6%.

Ideally, you should lower the temperature at night to about 5 °C. The heating should be turned down as early as two hours before you go to bed.

You should only reduce the temperature on the radiators at night, not switch them off completely, to prevent the room cooling down completely. If the room cools down completely, a higher heating water flow rate will be required to heat it up again.

Curtains hanging in front of radiators or furniture right in front of them will hinder the circulation of heat throughout the room. The heating system cannot achieve its full effect and must deliver more heat. That increases your heating bills.

When airing the room, open windows fully for a short time (about five minutes) instead of leaving them slightly open for a long time. Windows that are slightly open bring in little fresh air, but allow a lot of heat out.

Switch the heating system off while you are airing.

Ensure that windows/doors are well sealed otherwise a lot of heat will escape.

Curtains and shutters should be closed at night. That reduces rapid heat loss and keeps cold and draughts out.

Keep temperatures at the following levels: playroom, study, living room 20–22 °C, kitchen and bedrooms about 18 °C, hallway 15 °C.

Economical water use = lower heating bills

The use of water saving flush valves in toilet cisterns reduces water consumption. A conventional cistern consumes three times as much water as a cistern with a water saving flush button (1x flush consumes about 9 litres of water).

You should repair dripping water taps immediately otherwise your water consumption will become very high.

Water saving shower heads and taps are highly recommended.

Take a shower instead of having a bath. A full bath uses three times as much water and energy.

When brushing your teeth, you should use a cup and keep the water tap closed while brushing.

When using your washing machine, always wash a full load, skip the prewash part of the cycle, and wash at 60 °C instead of 90 °C. Pre-washing is only required for heavily soiled laundry.

Use economy cycles if your washing machine or dishwasher has them.

A clothes dryer uses twice as much energy as a washing machine for the same amount of clothes. Therefore you should dry clothes in a drying room or in the open air whenever possible.

Regular expert servicing keeps your heating system running smoothly

Regular servicing extends the service life of your heating system, its efficiency and ensures reliable, trouble-free operation. This is the only way to make sure that the energy from the fuel is used efficiently and cleanly, thus protecting the environment and saving on heating bills – without compromising high heating and DHW convenience.

The boiler, burner and control unit form a system like that of a car engine. If your car was in operation for the same amount of time as your boiler, it would cover more than 60,000 miles in a year. And all car owners know that they need to have a service carried out at regular intervals. Therefore your heating system should be serviced at least once a year, much like your car.

The benefits of regular servicing

  • Greater efficiency and extended service life of the heating system, together with greater operational reliability
  • Savings on heating bills and lower consumption of resources due to efficient use of the input energy (experts rate the potential savings at about 5 to 7 %)
  • Constant high level of heating and DHW convenience
  • Heat generated with reduced CO2 emissions due to economical and environmentally responsible operation

Servicing requires expertise. That means that your heating contractor is the best person to carry out regular maintenance, because a service professional will always check all system components thoroughly for contamination and wear. That also includes checking the safety and control functions.

Annual monitoring of the system on the basis of a maintenance contract is recommended, because that ultimately helps to save costs – not only will the efficiency of the system be improved, but a breakdown of the heating system usually ends up being more expensive for the user than preventive maintenance.
