New Boilers
Replacing your boiler is one of the most worthwhile investments you can make in your home. An ageing or inefficient boiler not only costs more to run, it can also leave you with uneven heating, unpredictable hot water and the nagging worry of something going wrong at the worst possible time. Whether your current boiler has reached the end of its life or you simply want to upgrade to something more efficient, Complete Heat Pumps is here to guide you through the entire process, from choosing the right system to having it professionally fitted and fully commissioned.
We work with Viessmann for gas boilers and Grant for oil-fired systems. These are trusted names known for their reliability, efficiency and manufacturer-backed warranties. Every boiler we fit is matched carefully to your home’s size, layout and hot water demand, so you’re not paying for more than you need or being left with a system that falls short.


Which Boiler Is Right for Your Home?
Understanding the difference between boiler types is the first step to making the right choice. A combi boiler heats water on demand without the need for a separate hot water cylinder or cold water tank, making it an ideal solution for smaller homes and properties with limited storage space. A system boiler works alongside a hot water cylinder to supply heat to multiple outlets simultaneously, which suits larger homes with higher hot water demand. A regular (or heat-only) boiler is the traditional option, best suited to homes that already have a cylinder and tank setup and want a like-for-like replacement.
Our RGI-registered engineers will assess your property and talk through your options honestly. We break our pricing down by property size, covering homes up to three bedrooms and larger, so you have a clear, transparent figure before any work begins. There is no pressure and no upselling. We recommend only what suits your home and your budget.
How We Handle Your New Boiler Fitting
From the moment you get in touch, our process is straightforward and well-organised. You can request a quote online or book a survey, and our team will take it from there. On the day of your fitting, our engineers arrive on time, work cleanly and treat your home with respect throughout. Once your new boiler is in place, we commission the system fully, walk you through the controls and make sure you’re confident before we leave.
We fit Viessmann gas boilers to the highest standards, and all of our installations are carried out in compliance with Irish Gas regulations. Every new boiler comes with a manufacturer’s warranty, and our work is backed by our own commitment to quality. Viessmann boilers are widely regarded as among the most dependable on the market, and as experienced fitters of both brands, we ensure your warranty remains fully valid from day one.
