How much is a new combi boiler in Gravesend?
Are you trying to work out how much it would cost for a new combi boiler install in Gravesend? Prices can vary from about £2500 up to £5000 or more.
Two elements influence the cost of a new combi boiler installation. The first is the make and output of the boiler you pick – buying a high output boiler from a well known manufacturer will be pricier than getting a lower output option from an inexpensive brand. The second factor is how difficult the installation job is – replacing your current combi boiler with another one in the same spot is cheaper as it’s not as time consuming for a heating engineer. If you have a standard heat only model and want to upgrade to a combi one, it will be pricier as extra labour and materials are needed.
Our suggestion is to talk to an expert. Explain what you’re after and have them examine your property and provide some options. This way, you can find out which boiler works best for your needs without breaking the bank. We at Gravesend Boiler Installers would be delighted to do a free survey and provide a quote – just contact us on 01474 554887!
Combi Boiler FAQ
What Combi Boiler Is Best?
If you’re looking for reliable heating in the UK, then you can trust these top 3 boiler brands: Viessmann, Vaillant and Worcester Bosch. Additionally, Ideal, Baxi and Main are also great choices for your home.
Can A Combi Boiler Run 2 Showers?
Are you thinking of fitting a Combi boiler in your home? You should bear in mind that these boilers typically produce 8-12 litres of hot water each minute – which is fine for one shower but not two running at the same time. The best solution for this is to install a Heat-Only or System boiler and hot water cylinder. Or why not try a storage Combi boiler? These come with their own integrated hot water tanks to boost performance and Vaillant and Viessmann make models with flow rates over 20 litres per minute – plenty for two showers!
Where Can I Fit A Combi Boiler?
You have the flexibility to install a combi boiler in any area of your home, giving you the choice to optimise your space, as long as the installation abides by all relevant instructions, gas regulations and building regulations.
Here are some of the common places you can install a combi boiler:
- Kitchen cupboard
- Utility room
- Airing cupboard
- Loft
- Garage
- Bedroom
Should A Combi Boiler Be Installed On An Outside Wall?
No – although it usually makes the installation easier and cheaper.
It’s usually preferred to install a Combi boiler on an outside wall because the flue pipe (also called a chimney) that takes away the fumes can go straight outside. However, if you need your combi boiler to be installed somewhere other than an outside wall, there are options. One of the most popular alternatives is a vertical flue. That is, your boiler’s flue goes up vertically and passes through to your roof to take the fumes away outside. This is quite common for boilers fitted in lofts or airing cupboards.
When planning your combi boiler installation, if your boiler isn’t going on an outside wall, it’s best to discuss your flue options with a Gas Safe Registered heating engineer or the boiler manufactures themselves. This is because boiler manufactures have different requirements and limitations with flues. So what may work safely for one brand may not work for another. So it’s always best to check.
Does A Combi Boiler Need A Hot Water Cylinder?
Combi boilers are not dependent on a water tank, as they access their water from the mains. If you have a Combi boiler and a water tank in your loft however, this suggests an incorrect installation.
What Makes Combi Boilers Go Wrong?
The main cause is sludge from the heating pipes and radiators getting into sensitive parts of the boiler and blocking them up.
To prevent this, you should get your heating system flushed out to remove any sludge when you install your new combi boiler. Then for further protection, you should have a magnetic sludge filter fitted at the same time as your boiler. This device, often called a Maganclean, traps any sludge from the heating system before it reaches your boiler. Then once a year, it’s serviced as part of your boiler’s annual service, which includes removing the filter and clean off any sludge that its caught in the last 12 months. These filters are really important and are a requirement of a lot of boiler manufactures guarantees.

This heritage has given them a name as one of the most dependable names in boiler technology worldwide today.
The Ecotec Plus Combi Boiler is one such example which has stood tall ever since its release around 15 years ago – retaining much of its original design despite other manufacturers making great leaps forward during this time period.

People living in Gravesend will recognise ‘Worcester’ when it comes to Combi boilers – and rightly so! Whilst they may not be innovators like Vaillant, they do manufacture great quality products . This British firm came about back in 1996 when ‘Worcester’ merged with German giant ‘Bosch’ , giving us what we now know as ‘Worcester Bosch’. Over time they’ve achieved an impressive standing due mainly one particular boiler: their renowned ‘Worcester Cdi’.
Worcester Cdi Combi Boiler (Now Called The Worcester 8000)
The first version of this model emerged back in the mid 1990’s and fast became renowned for its dependable build and superior design features .

As part of the Baxi Group, Baxi makes well-known Main and Potterton boiler brands. Baxi boilers are a great replacement for conventional boilers.
