At the Eden Project, as well as maintaining all the mechanical plant on site, there is also the need to maintain the living plant displays in the biomes and surrounding areas. This is done mostly by growing new specimens from seed or cuttings, and sometimes buying in new plant material.

Quarantine

Every seed/plant which comes to our nursery site is inspected for any unwanted pests or diseases, and depending on perceived risk, may be quarantined. All tropical material is quarantined for several months before it can join the main collections in order to eliminate the chance of a damaging pest outbreak in the biomes.

At the nursery there was initially a 2MW oil fired boiler which heated the main 5000m2 glasshouse, and also the physically remote quarantine houses. In 2009 this was replaced by a fully modulating gas boiler set 0-600kw, controlled by a custom programmed Priva BMS system and heated area reduced to 2000m2. At that time, the quarantine facility was not heated from the main system, but by a very basic local control gas air heater.

A reliable solution

In 2013 the basic gas air heater had deteriorated to such an extent in the warm moist conditions, that it was no longer economic to keep it in operation. It was replaced by a sturdy LPG fired cabinet modulating air heater (36-72kw output) and linked to the BMS system.
