Energy Efficiency Upgrades

System Protection

MagnaClean is already protecting nearly two million UK homes...

While energy bills are constantly rising, you could save up to 6% a year on your home heating with MagnaClean – That’s £66 for a typical three-bedroom house.

HDM’s most popular filter for UK homes is MagnaClean Professional2. It captures the black sludge and debris that damages boilers. It’s compact size and shape allows it to be fitted in tight spaces and the simple design means that installation and ongoing servicing is fast and trouble-free.

Controls

How can heating controls help with fuel bills?

Using the right boiler controls with a condensing boiler offers annual savings of up to £300 and can help to ease your home’s impact on the environment.

Central Heating controls give you the freedom to decide how your home is heated, making it warm when you need to, but switching off when you don’t.

Making small adjustments to your boiler controls can help to save money. By turning your room thermostat down by just 1 degree, you could save £55 annually.

Improving the energy efficiency of your home could also help, for example by installing cavity wall insulation.

Which heating controls do I need?

HDM Heating and Plumbing Central Heating Systems
All new or replacement boilers require a minimum level of controls installed alongside them, either:

• A timer or programmer with a room thermostat and thermostatic radiator valves (TRVs)
OR
• A programmable room thermostat and thermostatic radiator valves
If your central heating system includes a hot water cylinder, that will require a thermostat too.

What is a timer?

A boiler timer is a basic device that allows you to set times for your central heating.

What is a programmer?

A boiler programmer allows you to set different times for heating and/or hot water.

What is the difference between timers and programmers?

A timer operates your heating system at the same times every day whereas a programmer allows different heating times for different days of the week to suit your lifestyle.

What is a room thermostat?

HDM Heating and Plumbing Central Heating Systems
A room thermostat enables you to set the target temperature for a room. Room thermostats are usually best positioned in the hall or landing. They should be sited away from direct sunlight and clear of curtains and furniture.

What is a programmable room thermostat?

A programmable room thermostat enables you to set different room temperatures for different times of the day and night.

When set up correctly, a programmable room thermostat prevents the system from having to heat the house from a ‘cold start’. The control always maintains a temperature within the property and this ensures that the boiler is only ever ‘topping up’ the temperature in the home. As a guideline, target temperatures should be set at 21 C for comfort temperature and 15 C for economy temperature.

What is a thermostatic radiator valve (TRV)?

TRVs allow you to control the temperature of each room individually, thus helping to improve comfort in your home as well as saving money and energy. Most radiators will be fitted with these. Ideally, TRVs should be well exposed and not obstructed by curtains or blocked by furniture.

Water Saving

SAVE WATER, GAS, TIME AND MONEY
How efficient is your boiler?

CombiSave is a thermostatically operated valve that can be fitted to the majority of new and existing wall hung combi-boilers. By controlling the flow of water during the initial firing process, CombiSave accelerates the heating of water and reduces the amount of fuel required.

Independent tests show that as soon as you switch on your boiler, the first ten litres used in the process of heating water are wasted. As such, more gas than is needed is burnt, excess carbon is produced and time is wasted.

Why waste fuel, money and time waiting for your hot water?

Over the year, a two person household could save:

  • • Around 28,000 litres of water
  • • 611 kwh of gas per year<
  • • Around £250 off your water and gas bills and carbon savings of upto 130kg
  • • Up to 21 hours over the course of the year saved by not waiting for hot water
  • • Around 260kg–500kg of Carbon dioxide per year, helping the environment
  • *Figures based on independent tests by EA Technologies

Save water

CombiSave reduces the amount of water needed by the boiler in the heating process, saving an amazing 28,000 litres of water (four person household).*

Save gas

CombiSave helps make combi-boilers more energy efficient. As the time taken to heat up your water is reduced, you will use much less gas. And with a CombiSave fitted, you can turn ‘Pre-Heat’ off and save even more on your Gas bill, sometimes up to £75.00 per year!*

Save money

Reductions in use of water and gas can save you hundreds of pounds, and as CombiSave is a ‘fit and forget’ device, you won’t have to worry about lots of expensive repair bills.

Save time

The CombiSave will provide your hot water much quicker than the boiler, thus saving you precious time every day – and how can we put a price on that?

Save CO2

Reducing the amount of resources your home uses makes it more efficient and helps reduce your carbon footprint. Making small changes can make a big difference to the planet.
