Pre-heating the feed water to achieve an ideal boiler feed water temperature will allow the boiler to run most efficiently as the heat input required to raise the temperature of the water up is reduced. The difference between 140°F and 180°F in boiler feed water temperature equates to about a 3-4% difference in boiler efficiency.
Apr 11, 2012 · Boiler manufacturers provide factory default hot water supply temperature (HWST) reset control settings that rely on an outdoor air temperature (OAT) sensor being present. The reset control changes the HWST set point the boiler maintains as a function of OAT; as OAT goes up, HWST goes down.
Hot water boiler systems also have a high-limit temperature setting that triggers an automatic shutdown if the water temperature rises above that set point. If the high-limit temperature setting is too high, generally over 200 degrees Fahrenheit, the system pressure will reach an excess condition as well and start leaking.

A large easy to read display provides current system temperatures and operating status.
The aquastat on a hot water boiler is essentially a combination heating control. The aquastat monitors the water temperature in the boiler through the use of a copper bulb that stays in contact with the water inside the boiler and that shuts down the boiler automatically if the low- or high-temperature set point is exceeded.
Oct 17, 2014 · The temperature control is a dial numbered 1 to 6 with a dotted line between the 5 and the 6. I read somewhere a while back that it's most economical to run a boiler at its highest temperature. However my daughter has just had a Worcester Bosch fitted with an 'e' (for economy?) next to the 4 on the dial. So is here any guidance for boiler
Outdoor Temperature Reset In order to properly control a hot water heating system, the heat supplied to a building must equal the heat loss from the building. The heat loss is dependent on the outdoor temperature. It is therefore necessary to reset the supply water temperature based on the outdoor temperature.

The thermal element of a hot water boiler limit control: a) Measures pressure. b) Senses temperature, and changes it to a corresponding pressure. c) Must use a capillary tube. d) Measures the heat content of the boiler water. e) Is not used when the boiler has a modulating firing rate control strategy.
Control Settings for Steam Boilers The controls used on a steam boiler are similar in function to the same controls used on a water boiler, except they work off of pressure instead of temperature. Pressuretrols have subtractive differentials, similar to their water counterparts. Modulating pressure controls have additive differentials.
In large capacity boilers the injection type desuperheating is adopted for superheater temperature control. Reheater in power boilers can also be technically classified as superheaters, however the type of control adopted is mainly varying the heat available from flue gas side by bypassing the flue gas to the superheater side (The Babcock design) and the burner tilt to vary the radiant heat availability (The Combustion Engineering design).
Boiler, central heating and hot water cylinder controls . The controls fitted to a domestic boiler and wet central heating system should allow you to control when your home (and hot water if appropriate) is heated and the temperature it is heated to.
BriskHeat Temperature Controllers. All applications that require heat must be controlled. To meet this requirement, BriskHeat ® provides temperature control options ranging from bimetal thermostats to a network of digital PID temperature controllers for a heating system.
measuring realized savings over a heating season, the data collection offers a greater insight into the conditions under which the controllers “decide” to hold the boiler and how, if at all, adverse effects are created by dropping the low temperature limit (e.g., loss of thermal comfort).
PID temperature controls A PID is a three-mode controller that integrates proportional, integral, and derivative actions to provide stable and accurate temperature control. Its integral and derivative actions make it a suitable choice for complex thermal systems.
Central Heating Controls (127 products) There are several different types of Central Heating Controllers but essentially they all regulate and help to control the temperature of your home heating and therefore help control your heating costs.
modulation. For boiler plants greater than 16 boilers, the AERCO Control System (ACS) panel is required. Able to regulate overall plant output with precise accuracy, a boiler plant with ±4°F header temperature variation is assured under normal load conditions. It offers sequential or parallel operation flexibility, and user
If you have a condensing boiler, make sure that the return temperature is no higher than 55 degrees when heating radiators, to ensure efficient heat recovery. Radiators are generally set up for an 11C drop so the flow temperature should be 66C. Ideally this would be managed by a control system that measures actual pipe temperatures.
A boiler water temperature controller is just an on and off switch that controls water temperature. How simple can you get? It’s like a thermostat, but for water instead of air. Yet the terminology associated with the controllers — differential, switching action, immersion, capillary — creates
Temperature controls for your heating and hot water. Some boilers have separate controls for the temperature of the radiators and hot water. This allows you to set the temperature of the water that leaves the boiler to heat the house. If you lower the temperature, your boiler will operate as efficiently as possible.
