Best Floor Standing Boilers

Floor-standing boilers originally became popular as they were more powerful than the conventional wall-mounted. But as technology advanced, both wall and floor boilers now enjoy the same level of performance when it comes to your central heating. So, when it comes to choosing a floor-standing boiler, it is down to personal preference as well as how your home is set up. We take a look at today’s floor-standing boilers and review some of the very best you can buy.

What Are Floor-Standing Boilers?

By way of a quick and simple explanation, floor-standing boilers are boilers that are installed to sit on the floor, rather than be mounted on a wall. From a functionality point of view, floor-mounted boilers are no different to their raised counterparts, and can be regular, system or combi boilers. In fact, biomass boilers, due to their size and need for more storage, are typically floor mounted and can be located outside.

Floor mounted boilers were originally the most powerful and largest of the boilers, hence the need to locate them on the floor as they were too heavy to be mounted on most domestic walls or in a cupboard. But as boiler technology advanced, there really is no difference between the performance of wall or floor located units when it comes to the quality of the heating supplied.

However, by installing a boiler on the floor, you will need more internal space than a compact wall-mounted model so floor-mounted boilers are not necessarily suitable to smaller homes or apartments.

Are Floor-Standing Boilers Any Good?

While they are not as popular as they used to be, floor-standing boilers can be just as good as any other boiler when it comes to energy efficiency and providing hot water and heating your home. The main deciding factor as to whether you should opt for a floor-standing model is if you have the room. With space in many homes a premium, floor-standing boilers can be too bulky and are not as versatile as wall-mounted models, which can at least be tucked out of the way and give you more storage space underneath.

There are several reasons why having a floor-standing boiler as your new boiler could be a good choice:

  • You are replacing an old floor-standing boiler, so already have the right pipework and set up for installation
  • You have the space such as a utility or cellar which can easily accommodate a floor-standing boiler
  • Many of today’s modern floor-mounted boilers are not the beasts they once were, and there are compact models which can fit in an under-counter cupboard if you don’t have enough wall space
  • Your walls are not strong enough to hold a wall-mounted boiler
  • You are opting for a bio-mass boilers, which are all floor-standing.

However, when it comes to fully answering the question, ‘are floor-standing boilers any good?’, you do have to take into account the inconvenience and cost of installation, especially if you are fitting one for the first time. And it can be invasive too, as you will need to make room for the floor-standing unit, which may mean re-thinking your kitchen layout or creating space somewhere else in your house.

Pros & Cons of Floor-Standing Boilers

As with any new home appliance, it is important to weigh up the advantages and disadvantages before deciding whether it is the right choice for your home. Here are the main pros as well as cons to installing a floor-standing boiler.

Pros

  • The larger size of floor-standing combi boilers can offer better flow rates than many wall-mounted boilers
  • Many floor-standing boilers are now designed to be pretty compact so can fit under a kitchen worktop or under-counter cupboard, so can make the best use of your existing kitchen space
  • A new floor-standing boiler is the easiest and most economical way to upgrade an old boiler of the same type as you won’t have to make any significant changes to the pipework and so save on some installation costs
  • You can still get floor-standing boilers with a range of fuel sources, including oil, gas, LPG and biomass

Cons

  • The design of floor-standing boilers means that many are on the larger side, and so need more floor space than other types of boilers. This means floor-standing models are not really suitable for smaller homes
  • With the convenience of wall-mounted boilers, you will find less choice of floor-mounted boiler models than there used to be.

The Last Word on Floor-Standing Boilers

With all the functionality of conventional wall mounted boilers and available has heat only or combi, floor-standing boilers can still hold their own, but they also need their space. And despite manufacturers’ best efforts, they are not as compact as other types of boiler. But they are durable and can be powerful and can be space efficient if you have a larger property or don’t have sufficient wall space.

If you already have a floor-standing set up and want to replace an old boiler with a new boiler model, then upgrading can make sense as you have all the pipework in place. And if you are wanting to move away from fossil fuels such as gas and move to biomass fuels for your home heating and hot water system, then a floor-standing boiler will be a matter of course.

All of this means that at the end of the day, if you have the space, then opting for a floor-standing boiler is a personal choice and there are some excellent brands and models to choose from.
