Trust’s Polesden Lacey goes
green with new biomass boiler
Work has started on the installation of
a new, eco-friendly biomass boiler at
Polesden Lacey in Surrey. The boiler will
burn wood chips instead of oil, producing
one tenth of the CO² emissions that are
produced by the current oil-fired system.
The National Trust (NT) has employed
sustainable energy experts Baystar to
deliver the energy solutions for the estate
with completion of the project due in Q1
2017. It’s the second of several installations
planned for London and the South East
as part of the NT’s national “Renewable
Energy Investment Programme”.
In 2009, the NT set itself a target to
reduce the use of fossil fuels for heat
and electricity by 50% by 2020. Polesden
Lacey is one of the largest uses of oil in the
charity’s London and South East region.
The Trust is investing £500,000 to install
the new boiler and remove the old oil tank.
It’s expected that the income generated
from the Renewable Energy Incentive
Scheme will pay back this investment
within 12 years.
Polesden Lacey has been reliant on
up to 60,000 litres of oil per year to heat
the historic house. Climate control is
vitally important within the house for the
conservation of the museum-quality items

in the collection, which can be adversely
affected by humidity levels.
The biomass system will remove the
property’s dependence on oil and generate
897,000kWh of energy, which will heat
not only the house, but also the café,
gardener’s office and four cottages.
This will remove the environmental risk of
an oil pollution incident, and save around
157 tonnes of CO² from escaping into the
atmosphere. Increasing levels of CO² are
known to be a major factor contributing to
climate change.
The project aspires to source woodchip
from the Polesden Lacey estate and
surrounding properties in the future. The
aim is to become self-sufficient in terms of
our fuel supply by creating a sustainable
heating source.
The new heating system isn’t the only
way the team at Polesden Lacey are
working to reduce their CO² emissions.
Over the past six years the property has
halved its energy demands, by upgrading
eth Building Management System
controlling heating in the house and
through a range of simple measures that
anyone could adopt in their own home.
For example: saving energy installing draft
proofing to windows and doors.
Ernst Schweizer AG, a leading metal
engineering company serving the
construction industry, is boosting its
presence in the UK solar photovoltaic
market with the launch of its MSP range
of advanced solar mounting systems in a
drive to recruit distribution partners.
The Swiss company has identified
growing demand for its advanced
rooftop solar mounting systems among
EPC contractors, property developers,
housebuilders, commercial construction
companies and installers. The company has
an office in Reigate, Surrey, from where it
supports UK customers on both new-build
and refurbishment projects.
Schweizer believes that rather than
reducing long-term demand for renewable
energy, cuts to Government incentives
will boost interest in self-consumption
among electricity users such as offices,
manufacturers and cold-storage facilities
and also home owners, driven by the need
to lower electricity bills and reduce carbon
footprint.
Martyn Johnson, Schweizer Sales
Manager, UK and Ireland, said: “Solar is
growing strongly everywhere and it’s
important that UK suppliers know about
the quality and cost benefits of our market-
leading MSP range. We would like to hear
from electrical wholesalers, installers,
