As the winter season starts to take hold, we all know that boiler breakdowns will become more prevalent and these can frequently be caused by freezing condensate pipes. There are a number of recommendations available from various parties, including the HHIC, as to how these can be minimised and one of the recommendations is that condensate pumps should be fitted both in new and remedial situations.
Grundfos Pumps offer a useful product to perform this task – the CONLIFT. This pump comprises of just 2 models; the CONLIFT1 and the CONLIFT1 LS and both variants are supplied with an integrated NC/NO contact and cable so that if the overflow switch detects a high-water level, this can be used to switch off the boiler.
Their advanced design means they will operate automatically when condensate enters the collection tank from an appliance. The units then lift the condensate up to 5m in height and across a distance of several metres to the required drainage point. Another plus is that these units require minimal maintenance. The motor/pump unit can turn 180o on the tank which increases the flexibility of the installation process, a situation which is enhanced by the four symmetrical inlets that means the unit can be connected from any direction.
Thanks to the modular system, both options can be upgraded with either an alarm PCB and/or neutralisation unit which can be retrofitted in case changing conditions require this flexibility.
