Type of Boilers. Choose the right boiler for your home

Combination boilers

Great performance, great savings
Combination boilers deliver both central heating and instantaneous hot water without the need for a hot water cylinder. Modern combi boilers can now meet the demands of more than one bathroom.
Best used for
  • Better suited for homes with one bathroom
  • Hot water is generated only when it's required and does not need a water storage tank
  • Compact in size, so ideal for smaller homes

System boilers

For homes that use more hot water
System boilers are traditionally fitted with an unvented hot water cylinder which provides an increased capacity of hot water. The fact that the pump and controls are contained within the boiler casing counts towards a simple and space saving solution.
Best used for
  • Better suited for homes with more than one bathroom
  • Delivers a constant supply of hot water, so perfect for homes with higher hot water needs
  • Needs a water cylinder to store hot water

Regular boilers

A simple and effective straight swap solution
Also known as conventional boilers that are fitted in many UK homes. Regular boilers offer a simple and straight forward boiler replacement solution that traditionally requires a loft space to house the feed and expansion tank.
Best used for
  • Better suited for homes with multiple bathrooms
  • Ideal where a lot of hot water is used at the same time, in multiple rooms
  • Regular boilers are compatible with solar water and heat pump heating systems
Plumb2u Gas boilers range
We offer a wide range of Gas boilers from recognised manufacturers as Worcester, Vaillant and ATAG. Our range includes Regular, Combi and System boilers and you can find different sizes to suit all your needs.
If you are considering a new installation and you are unsure of which fuel type is the best one for you, please find some benefits and disadvantages associated with the gas boilers.
The main advantages of a gas boiler are:
  • Gas is cheaper than electricity. The Average price of Gas in the Uk is 4.17 pence / kW compared to 16.39 pence/kW of electricity. Therefore on long term Gas boilers work out cheaper for just the fuel prices.
  • Suits better bigger homes and families with multiple bathrooms. Because Gas boilers provide more power than electric boilers, they can be used for bigger homes with multiple bathrooms which can be used at the same time and newer gas boilers can be combined with advanced thermostat solutions to precisely control heating in the different areas of the house thus increasing efficiency and reducing bills. Check out our wide range of smart heating controls available on our website.
  • Gas is a cleaner form of energy compared to electricity produced from burning fossil fuels. If the electricity used for the electric boiler comes from renewable sources or nuclear power then it will create less pollution compared to a gas boiler but that’s not the case for now.
  • Leaves more spare capacity for electricity usage. Depending on the home and the use case but if the household requires a lot of current to be used at the same time then a gas boiler leaves more spare capacity to be used compared to an electric boiler that will take at least 2kW.
Some disadvantages of using gas boilers are:
  • Risk of gas leaks. Gas leaks can happen if proper maintenance isn’t carried out routinely, gas boilers are required to be inspected every year by a Gas Safe registered engineer, if inspections aren’t carried out then the manufacturer warranty can become invalid. The inspections cost between 50£ to 160£ and if you are a landlord you are legally required to carry them out.
  • Lower efficiency and higher costs for 1 bedroom flats. Gas boilers require more plumbing and space to be installed, they also require specific locations in the house to be installed. Gas boilers have lower efficiency than electric boilers but the efficiency difference is compensated by the price difference of the gas compared to electricity.
  • Higher chance of breakdowns compared to Electric boilers. Gas boilers have got more moving parts than electric boilers therefore the chances of a part breaking is higher and repair prices can range from 150£ to 400£.
  • Requires a bigger investment in installation. Gas boilers require more plumbing than electric boilers to work therefore new installations can cost more than an electric boiler installation which can be installed almost anywhere in the household.
  • Louder than electric boilers. On average gas, boilers are louder than electric boilers which don’t have moving parts but the newer generation boilers are quieter than previous ones and the noise level is getting closer to electric boilers.
To reduce the cost of your heating system, no matter if is electric or fuel type, we recommend you inspect your heating system (boiler, radiators and pipes) yearly and use maintenance products to keep your heating system up and running.

If you have questions about Gas Boilers here you can find some FAQ's
1. What type of boiler will I need?
Most households across the UK use a combi boiler for heating and hot water due to them being highly efficient, more affordable and smaller in size so you do not need as much storage room. 
The issue with combi boilers is that it becomes insufficient if you are a large household with multiple bathrooms and are looking for a higher demand of hot water.
In this instance, you would require the use of a system boiler. The system boiler is accompanied by a hot water cylinder tank to allow for storage of hot water. This means that you will have a constant supply of hot water to accommodate various showers and taps in the same household.
A regular boiler is the least common types of boilers. Regular boilers are used for houses with high demands of hot water, that use an older, traditional heating system. They are also used for properties in an area known to have low water pressure.
Both system and regular boilers require more storage room.
Still don't know which one work best for you? Get it touch with the manufacturer to request further details about products.
2. What KW boiler do I need?
KW is the amount of power output for the unit. The power that you will need will vary depending on the property. A good indication of what KW you need is by the number of radiators in your household. 
If you live in a small flat or apartment with only a few radiators, a small compact boiler will be ideal for both usage and efficiency.
A medium sized boiler will be required for an average house of three to four bedrooms, something between 24-30kw should suffice.
A much larger household with plenty of radiators would require a boiler with a significantly bigger output (around 35-42kw) to be able to cope with the demands of the property.
3. What courier do you use to deliver boilers and where do you deliver to?
We deliver in and around London using our own delivery vehicles. Delivery time is usually next working day, however on some rare occasions this may not be physically possible.
If a boiler is ordered for delivery outside of London, it will be dispatched directly from the manufacturer to your stated delivery address. Please note that this does rely on stock availability from the manufacturer. If there is a slight delay to your order, we will contact you.
4. Do you offer discounts on bulk buys?
Unfortunately, the price stated on the website is normally the lowest we can offer, however please feel free to get in touch before purchasing as we may be able to offer a slight discount on some occasions.
