How much heating capacity does a greenhouse need?

It follows from a heat-loss calculation for the specific site: cladding and screen U-values, covered area and envelope shape, the coldest design temperature, wind exposure and the crop's minimum night temperature. Two greenhouses of the same size in different climates can differ several-fold in peak demand.

Is pipe rail or air heating better?

Pipe rail gives even heat at crop level, supports internal transport and helps control humidity, but costs more to install. Air heating is cheaper and faster to install but gives less uniform conditions. Many projects combine a pipe-rail base with air heaters for peak demand.

Are heat pumps viable for greenhouses?

They can be where electricity is reliable and reasonably priced, where a low-temperature emission system is installed and where buffer storage smooths demand. In sites with very cold design temperatures a supplementary peak source is normally still required.

How much can energy screens reduce heating cost?

Screens reduce night-time heat loss materially, and double screens more than single ones, but the saving depends on climate, screen quality, gap-free installation and how consistently they are operated. Reviewing screens before enlarging boiler capacity is usually the cheaper order of decisions.

What should a heating quotation include?

Design conditions used, peak heat demand in kW, emission system layout, heat source type and efficiency, buffer volume, control integration, fuel or electricity consumption assumptions, installation scope and what is excluded — fuel supply, gas connection, chimney works and civil foundations are common exclusions.

HEATING

Greenhouse heating systems for commercial production

Heating is usually the largest operating cost in a cold-season greenhouse, and it is decided at design stage. Source pipe-rail, air heating, boilers, heat pumps, buffer storage and screening sized from a heat-loss calculation for your site.

SeedMatchGroup is supplier-neutral and helps buyers compare greenhouse, seed, fertilizer, irrigation and agriculture project suppliers worldwide. It does not manufacture, distribute or sell equipment or inputs.

How is a greenhouse heating system sized?

A greenhouse heating system is sized from a heat-loss calculation: the covered area and envelope, the U-value of the cladding and screens, the coldest design temperature and wind exposure at the site, and the minimum night temperature the crop requires. That produces a peak heat demand in kW and an annual energy demand, which then determine the emission system — pipe rail, air heaters or a combination — the heat source, the buffer capacity and the fuel or electricity cost the project must carry each year.

Describe your project (optional)

A few words is enough. The Brief Assistant will expand it into a clear sourcing brief.

The more context you share, the sharper our sourcing shortlist. Nothing is shared with suppliers.

Which packages should the request cover?

Select every package you want included. Anything left unselected is treated as outside the scope, and we will flag it as a possible gap between suppliers. This is equipment and works only — recurring fertilizer supply is requested separately.
