The Differences Between Boiler Types

If your existing boiler has broken down, or you would like to upgrade your system, you might be confused about the right option for your needs. As there are various boiler types available, you must pick an option to match your specific needs and budget.

Here at GJS Plumbing & Heating Services, we are breaking down the differences between boiler types, which could help you make an informed choice.

Combi Boilers

A combi boiler is the most common option in homes across the UK. It is both a central heating unit and a water heater, as it can heat hot water in an instant by burning fuels like oil or gas.

Unlike regular boilers, a combi boiler doesn’t require separate hot water storage tanks, as it can heat water from a single unit. Also, the boiler doesn’t require cold water, and you will not need to install a feed and water tank in your loft.

It’s a wise choice for smaller families, as you can only use hot water from a combi boiler for one task. For instance, you could provide a loved one with a cold shower if you decide to clean dirty dishes in the kitchen sink. If this sounds like a perfect option for your household, reach out to our boiler engineer Essex team today for an installation.

Regular Boilers

A regular boiler, also known as a heat-only boiler, is the most traditional system and features three primary components:

  • The boiler
  • A cold-water storage tank
  • A hot water storage cylinder

It works by the boiler providing hot water to both the central heating or hot water storage cylinder. This type of boiler is a smart choice for large families, as it will allow people to use hot water at the same time in the home, and it is ideal for low water pressure areas. However, you will need room in the loft to install a cold-water feed tank. Also, you will need to wait to heat water after flipping a switch, and you may need to wait for hot water again after running a bath or shower.

System Boilers

System boilers are an advanced alternative to regular boilers, as they can provide hot water and radiator heating on demand. Often referred to as closed vent boilers, they are a perfect choice for homeowners who want a regular boiler without excess components, as they are built into the boiler.

It’s an ideal option for homeowners who live in areas with low mains water pressure or large families that frequently use hot water. Yet, you will need to wait for the hot water cylinder to heat up again once it has run out. While it is often more expensive than the alternative options, it provides greater flexibility in the home and requires less space than regular boilers.

UK Law for Boilers

Regardless of the option you choose, UK law requires all homeowners to own condensing boilers, as they are 90% energy efficient, better for the environment, use excess energy for heating, and they can even reduce heating bills.
