Boiler Pressure and Central Heating System Pressure -- Why

As the system is heated up, the water expands and more water is pushed into the expansion vessel. The diaphragm is pushed further into the air side, squashing the air pocket a little more and the boiler pressure rises. The fact that the air side can be squashed prevents a large rise in pressure which would burst the system.

3 Differences Between a Boiler and a Water Heater

They heat water rapidly for two different uses: hot water and home heating and are typically powered by electricity, natural gas, propane or heating oil. A boiler system heats water to the point that it boils, and the steam is used to transport heat throughout your house.

Renewable energy - Solar Water Heating - Worcester Bosch

Solar hot water systems (also known as Solar Thermal) are a renewable energy source that harness heat from sunlight by capturing energy which is radiated by the sun within solar panels or collectors. Solar Water Heating is not to be confused with Solar PV (PhotoVoltaic), which is designed to generate electricity.

HYDRONIC HEATING: How to Use a Hot Water Tank for Space

This is why the best system designs include a heat exchanger to transfer heat from the domestic hot water to the space heating water, without the two kinds of water mixing. Plate-style exchangers work best in this application, though they do need to be descaled every 6 months to 2 years by running vinegar through the exchanger with a transfer pump.

There a number of reasons why this may be happening:

Combining a geothermal heat pump with a boiler | 2016-01

The boiler provides supplemental heat to the indirect water heater when necessary. In cooling mode operation, any heat supplied to domestic water by the desuperheater is heat that would otherwise be dissipated into the earth loop. This is truly "free heat" given the alternative of dumping those Btu into the ground.

What temperature should a central heating boiler be set at

In a modern boiler system, it should be "reset" (adjusted, in simple terms) based upon outdoor air temperature. Whether you have a condensing boiler, or a non-condensing (typically cast-iron sectional) boiler will dictate how low of a return tempe

What is the best heating system for new home construction?

Without diving into the many details of each system type, your choices are, for the most part, as follows: electric baseboard, forced air systems (furnace or heat pump), and hydronic heating systems (fin tube baseboard, radiators, and/or radiant in-floor systems). As a reminder, hydronic systems use hot water from a boiler to heat your home

The steam boiler is an old convection heating technology dating back over 200 years and is most commonly found in old homes. Because steam boilers operate at a higher temperature than hot-water boilers, they are inherently less efficient than their hot-water cousins and are more finicky to operate.

Using Your Heating System to Heat Water | BuildingGreen

The other primary option for using a heating system to produce hot water is to install an "indirect" or "indirect-fired" water heater. This is a separate insulated water tank that is heated using hot water from the gas- or oil-fired boiler. The indirect tank is usually plumbed to be a separate "zone" on the heating system. One advantage of this
