Use a Vent Condenser to Recover Flash Steam Energy

2014-5-21 · Boiler efficiency: 80% Cost of fuel: $8.00 per million Btu ($8.00/MMBtu) A vent condenser could condense the flashed steam, transfer its thermal energy to incoming makeup water, and then return it to the boiler. Energy is recovered in two forms: hotter makeup water and clean, distilled condensate ready for productive use in your operation.

What size of boiler do I need for my home? | Viessmann

Modern advances in boiler technology mean that they are now more efficient than ever. In the past homeowners were often advised to choose an over-sized boiler to compensate for heat loss, this is no longer recommended. It will result in wasted energy and is likely to leave you paying more than you need to for your gas bill.

Boiler losing pressure? Causes of low boiler pressure

Does boiler pressure keep dropping? Your boiler losing pressure is an occurrence more natural than childbirth, and overtime (or, sometimes overnight) – they're bound to lose some water (pressure) and require topping up (or, repressurised). So if this is your boilers first rodeo – relax. And just top up the pressure (we'll tell you how, further down).
