It is normal for a boiler to cycle on and off to get your house to the desired temperature. Advantages: Hot water on demand does not run out everything is within the boiler which if under warranty means everything is covered for parts and labour via the manufacturer Better pressure in showers depending on your incoming mains supply Once fitted future replacements are straight forward.
On a sealed system meaning less chance of system corrosion Can often be fitted in a cupboard out of the way Disadvantages: Showers can be effected when someone else runs a tap replacing a conventional boiler with a combi can be expensive often not suitable for larger properties with large usage.
Conventional heat only A heat only boiler does exactly what it says on the tin. Advantages: Cheap to replace if the rest of the system is working ok more than one shower can run at any one time without effecting the pressure Most hot water cylinders have an electric immersion heater meaning if your boiler is not working you have a back up for hot water Disadvantages: Most of the moving parts are external to the boiler meaning that they would not be covered under a manufacturer warranty if you have a new boiler fitted.
Due to the way the hot water is heated it can run out of hot water if used in quick succession ie you have two or three showers in a row. Water pressure in showers is often terrible unless a shower pump is fitted.
Advantages: Fitted on a sealed system meaning that there is less chance of system corrosion build up sludge The pump is internal to the boiler meaning that it is covered under a manufacturer warranty should it go faulty.
Compatible with an unvented hot water system Disadvantages: Quite expensive to replace vs a heat only Back Boiler: Back boilers are slowly being phased out. The parts for this type of boiler are very hard to come by as many have been discontinued. Advantages: If serviced annually there is very little on them to go wrong so therefore they are quite reliable. Disadvantages: Very expensive to replace due to its location Not many parts are in circulation any more Very inefficient to run Expensive to service.

A: If your home still feels cold in certain rooms even with the heat turned on, your home may be unevenly heated or there could be an issue with heating delivery overall.

Live in a cold climate, but get lots of sun? Active solar heating may be the most efficient option for heating your home. Electric resistance heating can be expensive to operate, but may be appropriate if you heat a room infrequently or if it would be expensive to exte This article explains how to tell what kind of heating system you have installed.
We compare hot water heating systems hydronic heat or hot water boilers , warm air furnaces, and steam systems. We explain AFUE or heating system efficiency ratings and numbers. The articles at this website describe the basic components of a home heating system, how to find the rated heating capacity of an heating system by examining various data tags and components, how to recognize common heating system operating or safety defects, and how to save money on home heating costs.
Don't confuse the type of heating system you have installed since their means of making and distributing heat, their controls, and their equipment are mostly different.
We illustrate the basic types of residential heating systems just below. There are of course more sophisticated versions of furnaces and boilers such as high efficiency furnaces or boilers and condensing boilers. Above: A fan coil heater hung from a garage ceiling. The heat exchanger in a water to air heating system is then placed inside of an air handler or blower compartment where a blower fan circulates building air from return ducts to a plenum where air is blown across the heat exchanger and then the warmed air is delivered to the occupied space through additional warm air ducts or radiators.
Heating furnaces, boilers, and steam boilers may make use of different energy sources. Your heating system may use. Before we go on to illustrate the types of equipment that actually produce the heat to be used in a building we list the basic methods of heat distribution within a building. Air heating systems blow warm air into the room to warm the room and its occupants.
Hot water heating systems radiate warmth into the room by both radiant heating from hot radiators or baseboards and by warming air that circulates through the radiator, convector, or baseboard by convection.
Radiant heating systems warm room surfaces and occupants without directly warming the room air itself. Warm Air Heating Systems - Furnaces:. If the heat in your building is provided by warm air that flows out of ceiling, wall, or floor air supply registers into the occupied space, or if your heating system uses a water-to-air heating system then the air which warms the living space is probably being delivered through large or small diameter ducts, registers, air filters, and a furnace blower, and the air is being heated by a gas, oil, or electric furnace, or perhaps by a heat pump or a geo-thermal system.
Modern warm air heat furnaces use "forced air" - that is, a blower that circulates building air from return air registers through the heating furnace and pushes it into the occupied space through ductwork and supply registers. In modern furnaces the heating air flow direction may be "upflow" cool air enters at the bottom of the furnace and warm air exits at the top, or "downflow" cool air enters at the top and flows out of the furnace side or bottom such as in our sketch at left.
Older warm air heating systems used gravity warm air rises by convection to deliver heat to the occupied space without a blower fan. Sketch of a typical warm air heating system above left is provided courtesy of Carson Dunlop Associates Associates.
If the heat in your building is provided by warm or hot metal radiators, heating baseboards containing finned copper tubing, or wall convectors that look like a radiator but contain finned copper tubing, or if heat is provided by flexible rubber, plastic, or metal tubing run in building floors or ceilings, then the warm or hot water circulating in those devices is probably being delivered by piping circulating water heated by a heating boiler, or possibly by a steam boiler or a heat pump or geo-thermal system.
Modern hydronic heating systems use one or more circulator pumps to move hot water from the boiler through radiators or baseboards that deliver heat to the occupied space. Cooler water returns to the boiler for re-heating. Older hot water heating systems may have omitted the circulator pump s , relying simply on gravity warm water rises in the pipes by convection to move hot water through the building. A sketch of a typical hydronic heating system is shown at left.
Hot water radiators or baseboards are not shown in this sketch. What are we looking at when we're talking about oil-fired hot water heat?
It's helpful to form a simple working definition that helps understand the system. An oil-fired forced hot water or "hydronic" heating system is a collection of components which heats a building by heating and then circulating hot water through heat-radiating devices located in the occupied space. A "heating boiler" is a steel, copper, or cast iron "box" of hot water, connected to a loop of pipe and radiators or baseboards which runs around through the living area.
The same physical water stays in the boiler and is circulated by a pump so that heat is delivered to the living area. Burning oil makes hot gases which are used to heat the water before being exhausted outside. Pumps move fluids through the system. Safety controls of various types are installed at various points protect against a number of potential hazards.
A "steam boiler" delivers heat to the occupied space in the form of steam: the boiler literally "boils" water and sends steam rising up through steam riser pipes steam, hotter and less dense than air, rises by convection in the piping system and through steam radiators in the occupied space. If your heating radiators have valves which hiss and let air escape as heat is coming on your heat is probably being delivered in pipes which circulate steam from the steam boiler up through radiators in the occupied space.
At the steam boiler controls monitor the boiler pressure less than 0.
