Benefits of upgrading your gas boilers heating controls

Upgrading your heating controls can provide multiple benefits, including lower fuel bills, reduced emissions, and a warmer home when you need it.

Older gas boilers may only have the option of “on” or “off”, or limited timer capabilities that provide heating for the same periods every day. If you work during the week and spend the weekend at home, you may find this to be inefficient. Fully programmable heating controls allow you to have heat when you wake up, and again when you come home, and whenever you need it at the weekend – all without you needing to manually intervene.

This means that the heating isn’t in use when you aren’t at home, potentially making a great saving on your heating bills. For heating controls that can be managed by an app, you can add even more flexibility. If you are due to be home early (or late, for that matter) you can adjust the timer for that day while you are away from home. Your house will be perfectly heated for the moment you step through the door!

Another useful feature of upgraded gas boiler heating controls is that you can heat different areas of your home differently. No longer do you need to have a consistent temperature across your home set by a thermostat in one room. You can heat the bedrooms differently to your living room – perhaps you like it nice and toasty to snuggle up, or maybe you like the bedroom a little cooler to sleep better. It’s simple to set up with upgraded heating controls.

By having this fine control over all aspects of your heating, you’ll use less energy, which will reduce your bills and lower your carbon footprint. It’s a simple way to protect the environment while still getting the best for your own home.

What’s Included in Every NRM Installation

• Boiler unit + flue
• Standard installation (1 day typical, 2–3 days with extras)
• Controls: basic included, smart upgrade available (+€150)
• Magnetic filter & system cleanse
• Manufacturer warranty: 7–12 years (model dependent)

Extra Costs to Keep in Mind

• Flue extensions: +€300–€500 depending on distance/alarms
• Pipework/condensate upgrades: usually included, major reroutes quoted separately

How Long Does a Replacement Take?

• Standard replacement: 1 day
• With extras (pipework/controls): 2–3 days

We plan works to minimise downtime and leave your heating/hot water commissioned before we leave.

The benefits of replacing your gas boiler

Choosing to replace your gas boiler can also reduce your energy bills as modern gas boilers are much more efficient than their older counterparts. However, it isn’t just improvements in technology that make new gas boilers more efficient – wear and tear will play a part too.

Every year, as your gas boiler gets older, it naturally becomes less efficient. Due to physical limitations, a boiler can never be 100% efficient, but modern boilers are often in the mid-90s. Older boilers will most likely have started in the mid-80s, and year-on-year degradation could put them as low as 70%, or possibly even worse than that.

This affects the cost of the gas you use to fuel your boiler. If your boiler is 90% efficient, 90% of what you spend on gas is used to heat your home. If it’s only 70%, you’re wasting 30% of the money you spend on heating!

Another aspect to consider is how healthy your gas boiler is. A new boiler will be covered by a warranty and should provide many years of service before any issue occurs. Older boilers will break down more regularly, and you need to factor in the cost of repairs (and the inconvenience they may cause) when evaluating the case for installing a new boiler.

Finally, modern boilers are more compact than their older cousins. If space is at a premium, or you want to reclaim space in a cupboard, a smaller replacement gas boiler is the answer.

When To Get A New Gas Boiler

There are several indicators that it might be time to get a gas boiler replacement. While boilers may continue to function for decades, once a boiler gets above 15 years of age, it is likely to have become much less efficient.

If your boiler breaks down regularly, it’s another sign that it may be time to make the switch. When you try to use hot water or turn up the heating and the system doesn’t respond in the way you expect (cold water or no increase in the temperature), it may also be time to investigate your options.

Additionally, if your existing boiler has been declared unsafe, you have a back boiler or are making other upgrades to your home, it makes sense to get a gas boiler replacement.

What’s Involved In A Gas Boiler Replacement

If your gas boiler is being replaced like-for-like, for example, a combi boiler for a new combi boiler, it will be a matter of disconnecting and removing your old boiler and then installing the new one.

If you are changing to a different type of boiler, the replacement may involve more work. New pipes may need fitting, and cylinders may need removing, and so on.

Whatever the case is, you can be sure that the team at NRM will have it all under control. We are fully experienced in replacing all types of boilers, and we work safely and efficiently at all times. Your boiler will be replaced as quickly as possible whilst maintaining all applicable safety standards.

Keep in mind that we will need access to your whole house to allow us to check all aspects of the heating system.

Ian Connery

As owners Killian and Hayley are fantastic to work with!

All the work their team' have carried out for us on our home has always been impecable with such high attention to detail.

Great to have such a highly efficient Dublin Plumbing Heating and Gas Boiler Replacement company near me !!

Barbara Ledwidge

Killian and his team upgraded my entire heating system, including fitting a new boiler and manifold and fixing my underfloor heating. I cannot praise them enough, 100% recommend this company, superb work and highly friendly and efficient.

Dave Sheehan

Fantastic service from Killian and Phil at NRM. Phil the engineer did an excellent job on replacing the water tank in my apartment, as well as installing a dual flush & internal overflow toilet cistern kit and replacing sink taps. He left the place clean and was lovely to deal with.

Tracy Nagle

I would highly recommend NRM Plumbing. When I moved into my apartment, the underfloor heating wasn't working at all after being poorly maintained, plus my boiler needed replacing. Killian's recommendations to install a combi boiler with the addition of a new water tank, pump, manifold and controls was spot on and restored the whole system as if it were new. My place stayed toasty throughout the winter and the bills were very reasonable with the upgrades. The work was also very neat, completed to the highest standard and in just two days. All quotes were transparent and there were no hidden costs. Excellent!

Debbie Roberts

We could not speak more highly of Killian and his team. They installed a completely new heating system for us and were extremely efficient throughout the process. Every evening they left our home spotless, and they managed our last-minute changes with ease. Thanks to their professionalism and hard work, we’re looking forward to a warm and cosy winter!

Paul McGettrick

Have nothing but the highest of praise for Killian and the team at NRM Plumbing and Heating. Moved into our house just 10 months ago and noticed very quickly that the old oil-based heating system in it was costing us an arm and a leg. Decided to change to gas and went, on Killian’s advice, for a complete install of a new combi gas boiler, 10 new rads with TRVs, and new piping throughout (to replace the old gunbarrel piping). Phenomenal job done by Aido, Phil and Lar. Punctual, professional, reliable and an absolute pleasure to deal with. Entire job completed in 3 and a half days to a very high standard. Won’t look anywhere else for our plumbing and heading needs.

John O' Brien

Switched from oil to gas boiler in Firhouse. Killian and the team did a fantastic job for installation. Very clean and professional work, pleasant to deal with as well.

Declan Farrell

Needed to get a pump on my water tank replaced. From initial enquiry to job completed in less than a week. Transparent quote provided before the work was done. Have used NRM before but not for a job this big. Great speedy friendly service. Highly recommend

Tony Jones

NRM are the best. Killian, Adrian, Philip, Bryan and Reese did a full re plumb on my house. combi boiler, new tank, new pipes, radiators throughout. full bathroom and kitchen work. They are all very skilled and have pride in their work. Extremely professional and will do what's wright for you not what's easy for them.

Alan Cowzer

I wanted to replace my old oil boiler with a new one, and also to have the fixtures on 6 radiators replaced with ones which would allow modern TRVs to be fitted.
Killian responded to my request within 24hrs and surveyed two days later with the quote arriving later that day. Once I accepted the quote he gave me a start time of two weeks. He met all the promised response times etc., and was very helpful and professional.
The lads who arrived on the agreed date, Adrian & Reece were a delight to work with. Clean, non-intrusive (as much as they could be), and just went about the business in hand. Everything was done and fully tested in a day.
That was back in July, and the system has only recently been used in earnest but has been faultless now for two months.
I would 100% recommend NRM on the basis of my dealing with them.
