Moving Boiler To The Attic Or Garage

Moving Boiler To The Attic Or Garage

Key takeaways

  • Installing a new boiler, rather than moving your current one, can be more cost effective in the long run.
  • Old, inefficient and potentially hazardous back boilers can be converted into safe and economical combis.
  • Any type of boiler install/relocation should be carried out by a Gas Safe registered engineer.

If you believe you would benefit from moving your boiler to a new location, either for financial or safety reasons, the good news is that it’s possible to do so in most cases.

Can I Move My Existing boiler?

Depending on which type of current boiler you have in your home, and the proxemics of it’s intended location, it is in some cases possible to move a currently operational boiler from one part of the property to another.

However, it’s prudent to consider the move of a current boiler in terms of its monetary aspects before committing to such an undertaking. 

You should consider remaining warranty length, the overall condition/performance of the boiler, and the viability of its new installation location.

Why Installing A New Boiler Can Be The Better Option

There is absolutely no point in paying for the relocation of your current boiler if it’s on it’s last legs, the whole process would constitute a waste of time and money, and would lead to you panic buying a new boiler when (not if) it fully breaks down.

If your current boiler is older, less efficient than you’d like, or showing any signs of wear and tear, it may prove financially beneficial to install a new boiler in the location you intended to move your existing one to.

A fact of mechanical engineering and a more detailed design process, technological advancements in recent times have made modern boilers far more robust and efficient than anything made previously. 

The best way of ensuring optimum boiler performance is by proactively replacing ageing or faulty boilers at the earliest signs of degradation, this preventative step is far more prudent than reactive maintenance.

Modern Gas boilers are vastly more efficient than antiquated older models, reducing energy wastage which in turn saves you money!

Benefits Of Combi Boilers For Attic or Garage

Unlike conventional boilers, combi (combination) boilers link a home’s central heating system and water heating; no separate hot water tank is needed which is cleaner as it avoids potential rust or debris build up while providing instant hot water. 

This allows a compact boiler, succinct enough to easily fit into a standard kitchen cupboard, to thoroughly heat a home without stealing lots of space, especially when stored neatly in a loft or garage.

Combi systems are also easier to service or for boiler replacement due to their popularity, meaning greater part availability. 

Combi Conversions

If a brand new, efficient combi boiler sounds ideal for your home’s heating requirements but you have an older style of boiler currently set up, don’t worry as these can be converted into a combi as well.

Back boilers for example, are an old, antiquated variety of boiler that can be found fitted behind an open fireplace, instead of in its own designated area i.e a loft. 

These types of archaic heating system are poor in terms of comparative efficiency, performance, space saving, and safety compared to a modern combi.

Most people opt for a combi conversion as an upgrading of the entire system could be more efficient in the long run, and may ensure less future faults, reducing repair or maintenance costs.


An overhead, out of sight, secure storage space such as a loft or attic is a popular relocation choice for many people, and this area provides both positive and negative potential realities for homeowners.

The positives of this type of relocation include:

  • Creates space in higher traffic living areas within the property, a big upside if you decide to sell the house

  • Hides pipes and water circuit infrastructure

  • Less noise pollution 

The potential downsides to the loft or attic for relocation include:

  • Restricted access to the boiler when compared to a storage or airing cupboard

  • Insufficient gravity for conventional boiler functionality as storage tank would be on the same level

  • Subject to extreme temperature changes without adequate insulation


The Garage is an equally prevalent boiler deployment location, but again the complexities of such a move provide both pros and cons.

Potential upsides to a garage installation:

  • Greatly reduces operational volume

  • Conceals pipework more efficiently than some locations

  • Boiler is out of the way, creating more space in living areas

Potential negatives of a garage installation:

  • The boiler may face freezing as garages are often much colder than the inside of a property

  • If the garage is detached, the boiler pipework must be efficiently connected to the main property

If the relocation area of a loft or garage is proactively prepped for the installation of a new boiler e.g with suitable insulation, all safety regulations have been met, and the boiler itself has anti-frost protection technology, there is no reason either of these locations wouldn’t be a good choice to house your new boiler.
