How do you decide what size boiler I need?

A new boiler is usually sized around the property's hot water demand, number of bathrooms and existing pipework, rather than the size of the old unit.

Do I need a system flush with a new boiler?

It depends on the system. Years of sludge or debris in old pipework can work against a new boiler, so mention any cold spots or dirty water when you get in touch and I'll talk it through with you.

How long does installation take?

It depends on whether the job is a straight swap or needs changes to pipework, so timing is something I'll talk through once I know what's involved.

Can you move the boiler to a different location?

Mention it at the start if you'd like the boiler somewhere else, and I'll talk through what would be involved.

Will you explain the new controls after installation?

Ask, and I'll talk you through the new thermostat and controls.

Do you install combi, system and regular boilers?

The right type depends on the property and how you use hot water. Tell me what you have now and what you'd like, and I'll talk the options through.

What happens to my old boiler?

What happens to the old unit is something to agree when the job is planned. Ask about it when you get in touch.

Do you need to see the property before pricing?

Usually, yes. Pricing an installation sight unseen risks getting it wrong, so expect to talk it through and for the property to be looked at first.

Can you install a boiler in a smaller property?

Yes. Smaller properties usually need less output, and an oversized boiler can short cycle, so the size is worth talking through.

Do I need to be present for the installation?

Access to the property is needed throughout, so someone does need to be present for the full day of the installation.

Only need the current boiler fixing? Start with a repair

An old boiler running past its efficient life costs more to run every winter than a correctly sized replacement. The right boiler depends on the property, its hot water demand and the existing pipework, not just the size of the old unit.

Older systems often carry years of sludge and debris. If you think yours does, mention it when you get in touch, as the condition of the existing system is part of choosing and fitting a new boiler.

If you're not sure how the new controls and thermostat work, ask and I'll talk you through them.
