Overview

New Boilers Installed With Care And Expertise

An old or unreliable boiler can leave you with inconsistent heating, insufficient hot water and the worry of another unexpected breakdown. Replacing it can improve the reliability of your home's heating.

Choosing a new boiler isn't simply about replacing one appliance with another. The right boiler needs to suit your property's size, hot water requirements and existing heating system.

Our installation experience includes more than 1,000 boilers, built up over 20+ years in the heating industry. We can help you compare suitable options from established manufacturers without unnecessary upgrades.

From assessing your current system to installing and commissioning your new boiler, Delta Flow focuses on careful workmanship, clear explanations and a heating system that's straightforward to use.

What We Provide

New Boiler Options For Your Home

Different properties have different heating and hot water requirements. Whether you're replacing an existing combi boiler or considering a change to your heating system, we'll help you understand the available options.

Combi Boiler Installation

A popular option for homes with suitable water pressure and hot water demand, providing heating and hot water without a separate cylinder.

System Boiler Installation

Often suitable for larger homes with greater hot water requirements, working with a separate hot water cylinder to supply multiple outlets.

Regular Boiler Installation

An option for some properties with traditional heating systems, particularly where retaining existing tanks and pipework makes practical sense.

Boiler Replacement & Upgrades

Replace an ageing or unreliable boiler, improve your heating controls or consider a different boiler arrangement to suit your property.

How We Help

When Should You Consider Replacing Your Boiler?

A boiler doesn't necessarily need replacing simply because it's getting older. However, recurring faults, poor performance or an expensive repair may make upgrading worth considering, particularly if you're experiencing:

  • Frequent breakdowns and increasingly expensive boiler repairs
  • Inconsistent heating or unreliable hot water throughout your home
  • An older boiler that's becoming difficult to maintain
  • Changing heating requirements following a home renovation
  • A major boiler fault where replacement offers better value

What To Avoid

Mistakes We Help You Avoid

A new boiler is a significant investment. Choosing the wrong system or overlooking important installation details can lead to unnecessary expense, poor performance or problems later.

Choosing The Wrong Boiler Size

A boiler should suit the property's heating and hot water demands. We assess the requirements before recommending a suitable model.

Replacing Without Assessing

Simply fitting the same type of boiler isn't always the best option. We consider your existing system and whether changes would help.

Focusing Only On Price

The cheapest initial quotation may not reflect the full installation requirements. We explain the recommended work and what you're paying for.

Overlooking Future Maintenance

Manufacturer warranties and regular servicing matter. We register your warranty, explain the controls and offer continued support after installation.

Every Delta Flow installation includes a minimum 12-month labour warranty. Manufacturer equipment warranties range from 5 to 12 years, depending on your chosen boiler and the applicable terms.

We'll register your new boiler warranty, provide a handover pack and explain how to operate your controls. Ongoing support and servicing plans are also available.
