Wellington’s Specialist Hot Water Heat Pump Installer
For the Wairarapa, Wellington & Hutt Valley

Experienced plumber and gas fitter offers a range of hot water and home heating solutions including hot water heat pumps

A2W Plumbing & Hot Water Limited was established in 2023 by Anthony and Annie Jefferson after developing a strong interest in more environmentally conscious products and ways of doing business. 
"Keen to reduce our carbon footprint and reduce emissions, our commitment is both, contributing to saving the environment, as well as saving our customers money, by focusing on sustainable energy sources and newer technologies like hot water heat pumps."

Anthony and Annie have a long history in the plumbing and gas trades and Anthony is a certified plumber and gasfitter. As well as offering traditional plumbing and gasfitting services including installations, repairs, servicing, and maintenance, we can install hot water heat pumps - also known as air to water (A2W) heat pumps, and hydronic central heating.

Contact us if you would like to find out more, or you need our services.

Our experience and history in the gas and plumbing trades has led to where we are today

Annie and Anthony were dyed-in-the-wool gas enthusiasts who worked in the plumbing and gas fitting industry. With over forty years of combined experience, fifteen of those years operating a successful gas servicing company in Wellington, Annie and Anthony relocated to the Wairarapa to set up A2W Plumbing & Hot Water Limited.
"We started the business primarily to promote the more efficient hot water heat pump which is ideal for hot water and home heating. While gas is still a viable energy source, it is a fossil fuel - so for our customers already using gas, we aim to reduce their gas usage through three ways: remove gas and install a hot water heat pump, change out their old gas appliance for new, more efficient models, or service their existing unit to ensure that it is as efficient as possible."
