Why Choose Sweeney Renewables
We're a Donegal-based plumbing and heating company, and the official Irish agents for Orca air-to-water heat pumps — trusted by homes and businesses across Ireland and Northern Ireland.
Renewable heating, done properly
Sweeney Renewables trades as Frankie Sweeney Plumbing and Heating Ltd, based near Letterkenny, Co. Donegal. We put a strong emphasis on renewable energy products and energy-efficient heating systems, with a simple aim: to provide low-maintenance, environmentally-friendly heating for commercial and residential premises throughout Donegal and Ireland.
As official Irish agents for Orca, we supply and install European-made, SEAI-approved air-to-water heat pumps — alongside a full range of plumbing, central heating, underfloor heating, heating controls and rainwater harvesting services.
Our continued growth is built entirely on reputation and trust. As one of our customers put it, you get a second-to-none service from someone who "answers his mobile when phoned" — not a high-pressure salesman, but an expert and enthusiast for energy-efficient heating.
Our engineers are OFTEC and RGII registered — fully qualified and insured to work on oil and gas-fired heating systems, as well as renewable installations.
