new boiler

Thinking of getting your boiler replaced? - Read our Guide...


We know this sort of purchase isn’t one you make with your eyes closed, so we have put together a handy guide to getting a new boiler:

Why might I need to consider new boiler installation?

● Your boiler is no longer efficient enough

- Older systems will naturally be less efficient, meaning higher energy bills. Many boilers were only 60% efficient when installed, and over the years that efficiency would have reduced, so it may be in your best interest to look at a new boiler. New government legislation introduced this year means all new boilers installed from April 2018 will need an ErP efficiency rating of 92% or higher. These boilers will not only be more efficient giving you warmer homes but they are also much safer.

● Your boiler needs regular repairs and is no longer under warranty

- Sadly like anything in life, boilers can start to show signs of wear and tear and if your boiler is no longer covered by a warranty or guarantee this can become costly. If you are having to fork out for repairs on a regular basis it might be time to say goodbye and look at getting a new boiler installed.

● The boiler has been condemned and is irreparable

- if your boiler has been condemned by a Gas Safe Engineer it means your boiler could be dangerous or is not combusting properly, which can lead to fumes and emissions being released in your home. If the engineer has deemed your boiler unfit, he or she will have switched it off and made it safe. If they have told you it is irreparable your next step will be to get a quote for a new boiler to be installed. This is another reason why it is so important to have your boiler serviced regularly, as problems like this are picked up sooner.

● Parts no longer available

- Possibly the most common reason for needing to have a new boiler installed is the fact that older systems may no longer have the parts available for a repair. Whilst it may seem more cost effective to repair a broken boiler, if the parts are no longer manufactured this won’t be possible.

Which Boiler should I consider?

Combination Boilers

- Combination boilers also known as Combi boilers heat the water directly from the mains supply when you turn the tap on, so there is no need for a storage tank or hot water cylinder. This makes them very efficient as there is no need to constantly heat and store water.

Regular Boilers

- Often know as conventional, traditional or heat-only boilers. These boilers are linked to a water cylinder and also require space in a loft or area large enough to hold two storage tanks, one to feed the central heating and one to feed the hot water. This type of boiler is generally installed into older houses, where the property may have a more traditional heating and hot water system.

System Boilers

- A system boiler is similar to a regular boiler in that they are linked to a water cylinder, however, as more components are in the boiler such as the pump more is covered by the manufacturers guarantee.

How long does it take to install a new boiler?

This tends to depend on the age and type of your system, but typically a straightforward boiler installation will be completed within a day. However we can give you a better idea of time scales at the time of quoting.

How much is a new boiler likely to cost me?

The cost of a new boiler depends on several factors such as, which boiler type, the size of your property, whether you use gas, lpg or oil, and how many bathrooms you have. For a quick quote head over here to our website and click on ‘Get a quote’ for a rough idea.

Tareq's Tips #4. Six handy hints to help keep your house warm through a big chill…


It’s looking like we’re due to see some big drops in temperature through December and there might even be a touch of the white stuff. If your house isn’t keeping you as snug as a bug in a rug, we’ve got a few ideas here for easy ways to stave off the shivers and optimise your home heating throughout the winter season.

1. Cut out drafts

There are plenty of places around the home which can really let a draft in. Adding an insulation strip around your front door for example can really cut out the cold air, as can fitting a letterbox cover and keyhole cover - all easily available from your local diy shop.

2. Get your radiators working harder

At Roost Heating, we always say that bleeding your radiators regularly is a no brainer because it will help to ensure they are working as efficiently as possible. If your radiators are old then a power flush to clear out sludge build up is also a good idea. A simple diy solution to get your radiators working even harder is to add shiny silver foil behind them so more heat is reflected out into the room. If nothing seems to kickstart them into action and they’re still failing to keep you cosy, just get in touch and we can come up with a solution.

3. Achieve the optimum home temperature 

When the temperature drops, it’s often an automatic reaction to turn up your heating thermostat. It’s the thermostat’s job to maintain a constant temperature whatever the weather so fiddling about with it won’t make you any warmer. Just set it to the desired temperature (20 degrees is the general preference) and then let it work its magic. If your thermostat’s not working properly then perhaps it’s time you opted for something a bit smarter - like a nest* thermostat? Find out more here.

4. Get your boiler checked

A cold house can often be due to a boiler that’s not behaving itself. Strange clunking noises, radiators that are gurgling and not getting hot or never enough hot water can all be signs that your heating system needs an overhaul. Best to book a boiler check which may result in a simple boiler fix - and will certainly mean you can rest assured that your boiler is safe. If you do need a brand new boiler, we can advise you on the best, most economical boiler for you and we can install it too so you’ll be toasty in no time.

5. Consider your soft furnishings

Adding blackout blinds behind your curtains, or incorporating thermal interliners within your curtains can keep drafts around windows at bay and help keep your house that bit warmer. Even with modern double glazing, windows can let heat out. Similarly wooden or tiled floors can be warmed up by adding a woolly rug - or you could consider incorporating an underfloor heating system to really heat things up.

 6. Check out your chimney

If you’ve got an open fireplace that’s purely decorative , or a chimney that you never use, it might be creating a draft or taking heat away from the room. You can buy ‘chimney balloons’ at most diy shops and quickly and easily fill the gap. Obviously not suitable if you’re planning on lighting a fire, but definitely worth investing in if you just rely on your central heating system.

When it comes to home heating, economical and efficient heating solutions and clever ways to save energy, at Roost Heating we’re full of bright ideas. For further information on new boilers, underfloor heating, smart thermostats and more - just get in touch.
