What Are Heat Pumps?
What are heat pumps?
Heat pumps are renewable heating systems that take natural warmth from the outdoor air and move it into your home to provide heating and hot water. Unlike a boiler, which burns oil to create heat, a heat pump works like a fridge in reverse — it moves heat that's already there rather than burning fuel to make it. That's what makes them so efficient and so much cheaper to run.
How do heat pumps actually work?
An air-to-water heat pump pulls heat from the outside air using refrigerant technology, even when it's below freezing outside. It then compresses that heat to raise its temperature and sends it into your home through your radiators, underfloor heating, or both, as well as heating your hot water cylinder. The system uses some electricity to do this, but it gives out far more heat energy than the electricity it uses.
What types of heat pumps suit Irish homes?
Air-to-water heat pumps come in three main setups. Monobloc systems keep all the parts in one outdoor unit, with just water pipes running into the house, which makes them simpler to fit. Split systems have an outdoor and an indoor unit and can be slightly more efficient. Hybrid systems pair a heat pump with your existing oil boiler, giving you a back-up for the very coldest spells or for homes that aren't fully insulated yet. We'll help you pick the right one for your Sligo home.
What makes heat pumps different from a boiler?
Heat pumps give out several units of heat for every unit of electricity they use — usually three to four times more energy than they take in. There are no oil deliveries, no flue, no fumes, and no direct carbon emissions. They give steady, controllable heat and last for many years. They work best in well-insulated homes that use low-temperature heating like large radiators or underfloor heating.
What should homeowners know before installing a heat pump?
A heat pump needs to be properly sized using a heat loss calculation for your home — this isn't a guessing job. They run most efficiently in well-insulated houses, and you may need bigger radiators or underfloor heating to get the best from one. We carry out a proper assessment first to tell you whether your home is suited and what, if anything, needs upgrading. Heat pumps are an excellent fit for new builds, and for older homes that have been well insulated.
How Much Does Heat Pump Installation Cost in Sligo?
How much does heat pump installation cost?
A heat pump is a bigger investment than a boiler, and every home is different, so we give clear, honest pricing once we've assessed your property — no rough guesses. Your exact cost depends on the size of your home, how well it's insulated, your existing heating system, and the type of air-to-water heat pump you choose. We'll visit, calculate your heat loss, and give you accurate pricing for your Sligo home.
What affects how much a heat pump costs?
The system type makes a difference — monobloc units are generally simpler to fit than split systems, while hybrid setups that run alongside your boiler work out differently again. The size of your home and its heat loss decide how big a unit you need, which affects the equipment cost.
The condition of your current heating system matters too. If you already have good insulation and modern, generously-sized radiators, your costs may be lower. If you need larger radiators, extra insulation, or a new hot water cylinder, that adds to the work and the investment.
What's included in a heat pump installation quote?
Typically: supply and installation of the heat pump, mounting and positioning the outdoor unit, all pipework and electrical connections, system controls and programming, a hot water cylinder if needed, and full commissioning, testing, and a completion certificate. Extra work like radiator upgrades, insulation improvements, or underfloor heating is quoted separately based on your needs.
Do Heat Pumps Work in Cold Irish Winters?
Do heat pumps work in cold Irish winters?
Yes. Modern air-to-water heat pumps are built to work in cold Irish winters and can pull heat from the outside air even when temperatures drop below freezing. We've installed heat pumps across Sligo that keep homes warm right through the coldest weather.
How do they manage in our winter temperatures?
Today's heat pumps use advanced refrigeration technology and keep working even when it's a few degrees below zero. Irish winters are actually fairly mild compared to places like Norway and Sweden, where heat pumps are the most common form of heating. Our typical winter temperatures here sit comfortably within the working range of a good quality heat pump.
Do they work as well in winter as in milder weather?
A heat pump's efficiency does dip a little as it gets colder — that's just physics. But a properly sized unit is designed to meet your home's full heating needs even on the coldest day of the year for your area. It simply works a little harder in very cold weather while still keeping the house warm.
What helps a heat pump perform well in winter?
Correct sizing is the big one — an undersized heat pump will struggle when it's cold. Good insulation keeps the heat you've made inside the house. And low-temperature heating like large radiators or underfloor heating lets the heat pump run efficiently, whether you're in Sligo town, Manorhamilton, or out the country.
What about cold snaps and freezing conditions?
Quality heat pumps keep running in freezing weather and have a built-in defrost cycle to clear any frost off the outdoor unit. In a hybrid system, the back-up boiler can step in during an extreme cold spell, though that's rarely needed in Irish conditions.
Do I Need to Upgrade My Radiators for a Heat Pump?
Do I need to upgrade my radiators for a heat pump?
It depends on your existing radiators and how much heat your home loses. Many homes can keep their current radiators, while others need bigger ones to work efficiently at the lower temperatures a heat pump runs at. A proper assessment tells you exactly what's needed for your Sligo home.
Why do radiators matter for a heat pump?
Heat pumps work best at lower water temperatures than boilers. A boiler heats water very hot, while a heat pump runs cooler for longer. To give out enough heat at those lower temperatures, your radiators need to be big enough for each room.
When can you keep your existing radiators?
If you have modern, generously-sized radiators and decent insulation, your current radiators will often do the job. A lot of Irish homes already have oversized radiators that were fitted for hot boiler systems but work grand when run cooler for longer. Homes with newer or recently upgraded radiators usually need little or no change.
When do you need to upgrade radiators?
Small, older radiators made for hot boiler systems may need upgrading or adding to. Homes that lose a lot of heat through poor insulation might need bigger radiators to make up for it. Single-panel radiators in larger rooms often benefit from going to double or triple-panel ones with more surface area.
Are there alternatives to upgrading radiators?
Yes. Underfloor heating works brilliantly with heat pumps because it runs at low temperatures naturally. Adding underfloor heating to key rooms like the kitchen or living room while keeping radiators elsewhere is a popular option. Fan-assisted radiators can also work well at lower temperatures.
What Heat Pump Brands Do You Install in Sligo?
We supply and install premium air-to-water heat pumps from Daikin, Mitsubishi and LG — three of the most trusted names in the business. Daikin's Altherma range, Mitsubishi's Ecodan, and LG's Therma V are all proven, efficient systems with strong reliability and good support here in Ireland.
We're not tied to a single brand we provide a varied service.
