Oil Boiler Installation and Replacement in Derby

Etta Plumbing & Heating Services installs, replaces and services oil boilers in Derby and across Derbyshire. Our engineers are OFTEC registered (C100278), and we have been heating Derby homes and businesses since 1997.

Oil boiler installation in Derby is a need that reaches well beyond the city. Many homes in the villages of Amber Valley, South Derbyshire, Ashbourne and Uttoxeter are off the mains gas network, so oil is how they stay warm. If that is you, you need an engineer registered for oil, not just for gas.

Oil boiler installation in Derby

Every oil boiler job starts with a survey, not a sales pitch. We visit your home and look at the existing boiler, flue, pipework, tank and hot water demand, then recommend a boiler that fits. Quotes are free and no obligation, with evening appointments if daytime does not suit.

Sizing matters more than most people expect. A boiler that is too small struggles on cold mornings, and one that is too large cycles on and off and wastes fuel. We assess sizing before we quote, so the price you see is based on your house.

All modern boilers we sell and install are condensing boilers, which are up to 40% more efficient than older conventional models. New boilers also come with up to 12 years' manufacturer's warranty. Our boiler installations and replacements page covers the wider range we fit around Derby.

Oil boiler replacement in Derby: when it makes sense

A boiler does not have to fail completely before it is worth replacing. These are the signs we see most often on oil systems around Derby:

• The boiler is 10 to 15 years old or more.
• Breakdowns are becoming more frequent.
• A repair quote is more than a third of the cost of a new boiler.
• Fuel use is creeping up while your habits have not changed.
• The boiler is noisy, or there are sooty marks or a smell of oil nearby.

If you smell oil or see smoke, turn the boiler off and call us before using it again.

As a rule of thumb, if a repair costs more than a third of a new boiler, especially on a unit that is 10 to 15 years old or more, replacement usually makes more sense. Our guide to the signs you need a new boiler, not another repair goes through it in more detail.

What happens when we replace your oil boiler

Here is how a typical oil boiler replacement runs for a Derby customer:

1. Survey and quote. We assess your home, the existing system and your hot water needs, then give you a fixed price wherever possible.
2. Booking. We agree a date that suits you.
3. Installation. Most boiler swaps are completed within a single day. Relocations and system changes take longer.
4. Power flush. Every boiler installation includes a central heating power flush, which clears sludge from the system so your new boiler is not fed dirty water.
5. Commissioning and handover. We test the boiler, explain the controls and give you the paperwork for your records.
6. Guarantee. Our work is guaranteed. If something is not right, we put it right.

Tanks, flues and fuel lines

An oil boiler is only as good as the system around it. During the survey we check the tank, the fuel line and filter, and the flue route, because problems in any of these can affect safety and performance whichever boiler goes in.

If something needs attention, we explain what and why before any work is agreed. If you want the boiler moved to a new location, tell us at the quote stage so we can price it properly after the survey.

Oil boiler servicing in Derby

Oil boilers should be serviced once a year. A yearly service keeps the boiler efficient, catches small faults before they become breakdowns and is often needed to keep the manufacturer's warranty valid.

We service oil boilers across Derby and Derbyshire, with scheduled servicing available. See our boiler repairs and servicing page for how it works.

Thinking of switching from oil?

Some Derby customers ask whether they should move away from oil. The answer depends on the property. If mains gas runs to your road, a gas connection and boiler may be possible. If it does not, LPG boiler installation is the other common choice.

We work with natural gas, oil and LPG, so we can give you a straight comparison rather than steering you towards one fuel. Our oil, natural gas and LPG overview explains the differences.
