At the lowest point of the system. Old-fashioned low efficiency boilers have own at the bottom of the heat exchanger.
Note: Residential boilers should rarely if ever be drained.

When do you know when a backflow pressure valve goes in your boiler?
You see and hear water flowing out of it's drain tube into the floor drain.
How do you lower the water level in my boilers sight tube its too high im not getting enough heat to my second floor?
There should be a drain valve on the boiler. Drain it to the desired water level there.
How do you test a safety valve of a Boiler?
Raise the pressure in the boiler until the valve relieves and note the pressure at which it does so.
What is the application of boiler stop valve?
Stop Boiler Valve (or Crown Valve) is installed on an outlet line of a boiler. It's purpose is isolation of a boiler from a downstream steam line. Its position may be either open or close, it cannot be used for throttling of steam.
How do you size a boiler relief valve?
The relief valve should be at least as large (in BTU/hr capacity) as the input of the boiler. A 3.5 million input boiler would need then a relief valve to handle at a minimum 3.5 million BTU/hr.
How do you drain your baseboard radiators?
If there is no drain valve at the radiator you can drain the system at the drain valve on the boiler

How to drain a radiator in the house?
Not for the faint of heart! For a Combi/Evaporation boiler: Switch off the boiler. Take a reading of the boiler water pressure gauge. Shut off the radiator's thermostat valve(if fitted)/supply valve and return valves, connect a hose to the drain and put the other end into a large container below the level of the bottom of the radiator. Open the draincock first and then the air bleed valve and let the radiator drain. Close the draincock. When refilling the radiator put the anti-corrosion treatment in first then open the thermostat valve and return valve as wide as possible. when the air is expelled, close the air bleed screw. Using the fill loop restore boiler pressure. Put all thermostat valves(if fitted) to max and fire up the boiler. After the boiler has run for 10 minutes, switch off, or so go to the highest radiator and bleed out the air. WARNING: the water/steam will be very hot and likely to spit. Use a cloth as a barrier and to mop up any spills. Recheck the boiler pressure and top up as necessary.

What is the feed check valve of boiler?
The feed check valve of a boiler is on the line coming out of the boiler it is usually to prevent the water from going back in to the boiler its coming out of so it would build up excessive amounts of pressure which will cause the t&p valve to blow temperature and pressure
