Centre owners hope for "significant cost savings" and increased footfall and sales during the winter.
Bridgend Garden Centre will also benefit from the income generated via the Government-backed Renewable Heat Incentive, guaranteed for 20 years.
VG Biomass is the biomass arm of renewable technology company, VG Energy. VG Energy director Stephen Hamilton said: "With oil prices soaring 50 per cent over the last five years, heating a garden centre via oil is becoming increasingly expensive. Biomass heating is now becoming an attractive proposition for garden centre managers and owners as it helps to significantly reduce the running costs of the business.
He added: "By switching to biomass heating, a garden centre could save up to 70 per cent on its current fuel bill. Not only that, the business will earn a guaranteed quarterly income for 20 years via the Government's Renewable Heat Incentive. The Return on Investment is as high as 25 per cent, whereas the payback period is as low as 2.4 years to five years depending on the boiler size."
