GCR Feature: All fired up: Heating a garden centre

How you heat your garden centre can encourage customers to browse for longer and keep stock dry. Specialists Powrmatic give us the lowdown

An effective heating system will ensure that customers are comfortable during their visit and encourage them to browse for longer periods of time. As many garden centres have relatively low levels of insulation, the heating will also help to prevent condensation and stock damage. There are two types of heating technology that can be used to provide ef?cient solutions for the types of spaces found in garden centres.

Where & when

The heating system needs to suit the layout of the space as well as its physical structure. In some cases this will mean using different types of heaters for different areas to avoid cold spots and deliver optimum results.

Enclosed spaces

Enclosed spacesWarm air heating is usually the best solution for enclosed spaces within a garden centre. Usually the heaters will be mounted at high wall or roof level while ensuring that the merchandise displays do not obstruct the even distribution of heated air.

However, if the space is likely to be recon?gured on a regular basis, ?oor standing heaters with directional warm air outlets might provide greater ?exibility to accommodate future changes in layout.

High ceilings

If any area of the garden centre has a high roof then warm air will naturally rise, producing a temperature gradient between ?oor and roof. This potential waste of energy can be minimised by the use of destrati?cation fans mounted just below the roof to circulate warm air back to low level, thus saving energy. Areas that are partially open to the outside, and therefore undergo constant air changes, may bene?t from radiant heating as it does not directly warm the air but will warm customers as they browse.


garden centreDue to the temperatures attained by radiant heater emitters, they will need to be positioned a reasonable distance from people and stock. Particular care must be taken with positioning in the vicinity of tall plants to avoid damaging them, and to ensure that plants and stacked stock do not ?shade out? other areas from the radiated heat.

Cost and control

Having the correct heating system and controls will ensure facilities are heated with minimum energy consumption.

By setting up a zoned control system it may be possible to reduce temperatures in areas where people are active, while maintaining higher temperatures where people are stationary, such as caf?s.

Using timed control to switch the heating on before the centre opens will ensure the building is warm when people arrive. The morning pre-heat period can be combined with temperature optimised control to vary the pre-heating period, so that the heating will be delayed on warmer days, using less fuel.

Warm Air Heating

The source of the heat can be a gas or oil ?red burner in the appliance itself, hot water from a centrally located boiler or heat pump, or an electric element. Fuel sources for warm air heaters include mains gas, LPG and oil, as well as the ability to connect hot water heaters to biomass boilers.

Radiant Heating

garden centreRadiant heating is typically gas ?red (mains gas or LPG) and is provided either by suspended radiant tubes or radiant plaque heaters which may be suspended or wall mounted. Both types of radiant heaters emit infrared radiation from hot surfaces. Radiant emissions only warm objects, such as people, that are in the ?direct line of sight? of the heating source ? this needs to be kept in mind when positioning radiant heaters.
