Your guide to heating your home

Your guide to

It’s perfectly natural to want to feel snug and cosy in your home. Whether you’re

relaxing in the evening or taking a hot bath or shower, there’s no better feeling than

the warm glow of a comfy house.

In the UK, providing heat and hot water in homes accounts for around 65% of domestic CO2 emissions, source: Energy Saving Trust. There are lots of things that you can do to stay warm without hitting the environment hard. By using the right boiler for example, you won’t just help cut CO2 emissions, you’ll cut your bills down to size too.

That’s where this guide can help, featuring advice on finding the right boiler and tips on heating your home efficiently. So don’t let heating your home put a freeze on your finances. Stay warm, cut costs and start saving energy straightaway.

All energy savings facts and figures are provided by the Energy Saving Trust, are current at the date of going to print, May 2010 and are based on a typical 3 bedroom semi detached house and paying a gas price of 3.67p/kWh and an electricity price of 12.50p/kWh.

How will

you spend

your savings?

By replacing an old G rated boiler with a new high efficiency condensing boiler and improving your heating controls, you will significantly cut your home’s carbon dioxide emissions and could save as much as £225 a year – around the price of a pampered break for two in a country hotel.

(Source: Energy Saving Trust May 2010)

Did you know?

If everyone in the UK with gas or oil

central heating installed a high

efficiency condensing boiler with full

sets of heating controls, we would

save enough energy to heat nearly

1.7 million homes for a whole year and

save around 3.8 million tonnes of CO2.

New condensing boilers are much more efficient, converting around 90% or more of fuel into heating your house and hot water. That’s better for the environment and great news for your bills. And because you’ll start saving money from day one, your new boiler could soon pay for itself.

for you

and your home.

COMBI BOILER

Combining an efficient water heater with a central heating boiler, these space-saving boilers give you instant, on-demand hot water. Because they don’t use an extra hot water tank, they don’t need to heat a cylinder or reheat cold water. Which means they’re economical too.

Ideal if...

…you live in a small house or flat, or you’re short for space. They also make an excellent choice if you currently have a cold water tank in your loft but you want to convert your loft into a room.

SYSTEM BOILER

Ideal if...

… you have a larger home or family. You can also keep your loft space free, although you’ll need an airing cupboard. You can set your heating system so there is normally hot water available when you need it.

The exception would be when you use more than expected or at different times from normal, when you might have to wait for it to heat up more water.

OPEN VENT BOILER

A system boiler heats your water and stores it in a separate cylinder. This means you’ll need an airing cupboard or other space for the tank. However, they need less space than traditional open vent or heating-only boilers. The boiler also lets you run hot water all over the house without the others running cold.

Ideal if...

... you already have an open vent boiler, because it’s relatively cheap to switch to a more efficient open vent sealed system. The water pressure is low though, and you may only have drinkable water from one outlet.

This type of system uses two water tanks in the loft and a hot water cylinder in the airing cupboard. So it can take up a lot of space. You can run showers, taps and baths at the same time, but the cylinder will take a little time to reheat cold water.

Look out for the logo...

If you’re upgrading your boiler, look out for the Energy Saving Trust Recommended logo. This is your guarantee you’ve chosen a great model that will help you save money and energy. All npower approved boilers carry this logo.

Which boiler is right

for me

Every home and family is different. So it’s

important to pick a boiler that’s right for

you. Too small, and it might struggle to

keep you warm. Too big, and it might bring

you high energy bills. This handy guide will

help you choose…

Heating systems

It takes more than a new boiler to heat your home efficiently. Heating controls also

help you save money and energy, installing a room thermostat can save you around

£55 a year (Energy Saving Trust).

Get the right system in place

allows you to set the temperature you want and the ideal location for your thermostat should be in the hall. It responds to the temperature around it, so when the room is warm enough, the thermostat will send a signal to the boiler to stop supplying hot water to your radiators.

• Time switches and programmers let you control when your heating and hot water

switches on and off. They can be mechanical or digital. Time switches can only control one function, such as heating hot water, while programmers can control both heating your home and heating your water.

• Boiler thermostat. You’ll find this type of thermostat on your boiler. It controls the temperature of water leaving your boiler for

the radiators and hot water cylinder. It also stops the boiler overheating. If you have a room thermostat, you can set your boiler thermostat to a high setting in winter and a lower setting in summer. You can then control your room temperatures using individual thermostatic radiator valves or room thermostat.

• Cylinder thermostat. If you do not have a combi boiler, then your hot water will be stored in the hot water cylinder or tank, which is normally found in your airing cupboard. The thermostat will control how hot your hot water is. It is best to set the thermostat at 60o_{C. This will keep your} water hot enough to prevent the growth of potentially harmful bacteria, but any hotter will use more energy than you really need.

• Thermostatic radiator valves, situated on your radiators, these allow you to control the

temperature in individual rooms. Each thermostatic radiator valve senses the air temperature around it and works to maintain your chosen temperature. It’s easy to fit these valves and you can use them to turn your radiators on or off.

Other heating systems

home using electricity, especially if your area doesn’t have a gas supply. They run on off-peak electricity tariffs, such as Economy 7. The heater switches itself on during off-peak hours – usually at night – storing the heat to release the next day.

• Direct electric heating includes systems such as electric fires, panel heaters and ceiling heating. However, they’re not economical to use for all your heating needs, and they’re not great for the environment either, so it’s a good idea to use them sparingly.

Switch to gas home heating

and you could save money!

Finances

Here is a quick re-cap on how to save

money and energy while staying warm:

• Don’t overheat – lowering your thermostat

by just 1°C could save you around £55 a year. (source: Energy Saving Trust).

• Stick to 60˚ - if you have a hot water

cylinder thermostat, keep it at 60˚C.

• Keep them closed – if you’re too warm,

turn the heating down rather than opening the windows.

• Switch off – Have your heating and hot

water on only when necessary, also, only use direct electric heating systems when needed.

• The right setting – set your boiler

thermostat on a high setting in winter and a lower setting in summer.

• Go for the middle – turn your radiator

thermostat to the middle setting, then turn up and down a notch until you’re comfortable.

• Changing rooms – use your radiator

thermostat to keep the temperature higher in the rooms you use a lot and lower in the rooms you don’t.

• Wrap in a jacket – a thick insulating jacket

for your hot water tank costs around £15, but can save you around £35 a year (source: Energy Saving Trust). It should be at least 75mm (3 inches) thick.

Take a shower..

Taking a shower instead of a bath can use as little as a third of the water. However, be aware that many power-showers will use more water than a bath, if you tend to shower for more than 5 minutes. To be really savvy you could swap your power shower’s head for an aerating shower head. This type of shower mixes air into the flow to keep pressure high but reduce the water used. Believe it or not, the bubbles feel fab. By replacing their inefficient shower head with an aerated shower head a four person family could save around £50 a year in gas bills, and around £75 in metered water bills.
