heating, ventilation & services It is also highly recommended for the condensate pump to


be connected to a Ground Fault Interrupter (GFI) circuit. Go for a small, powerful pumping unit that can be floor or


wall mounted. It should come with an auxiliary external overflow switch that will shut down the appliance or alert the consumer in the event of overflow. It should also include all necessary hardware for ease of installation; 6m of vinyl tubing, inlet adapter, discharge adapter. Another good option is to fit an acid neutraliser and pump


specifically designed for the disposal of acidic condensate from gas boilers. Look for a pump that incorporates a tray with a neutralising


agent and a low level set point. These are designed so that as the boiler starts, the condensate runs into the tray. At a fixed higher set level a float switch can be set to activate the pump and the neutralised condensate is pumped out through the non-return valve. Choose one that is environmentally friendly, small and powerful with a quiet and light design that can be floor or wall mounted. They’re best with a pumping height of up to 4.5m and a maximum flow rate of 342litres/hour vertically at a mean temperature of 35 degrees C. A great example of where such pumps can provide the perfect


heating solution is in an older property in a rural area where the drainage isn’t suitable to allow for gravity drainage and where the waste water discharges to a septic tank.

Guidelines for the disposal of acidic concentrate recommend


it be neutralised prior to running into the foul drainage system to the tank (because it is detrimental to the friendly bacteria that break down effluent). In such a case, the safest and simplest option is to install a


condensing pump with built in acid neutralizing chamber – overcoming both installation problems with one easy-to- install product. Many industry professionals find such pumps to be the best


solution for pumping away neutralised acidic condensate when the alternative would be several runs of unsightly pipework or an external lime chipping soakaway. They find the compact units are incredibly easy to install and have been well proven in many domestic household jobs. And remember, a condensing boiler will always have a better


operating efficiency than a non-condensing one, due to its larger and more efficient heat exchanger. The benefits of condensing boilers are therefore quite clear.
