Green by Nature. Repairing Old Radiators - How to Install or Repair Heating, Ventilation & Air Conditioning Systems - DIY Plumbing. DIY Advice. Intro Many older homes are heated with steam or hot water radiators. Newer homes may have convectors. You can make minor repairs to radiators, but leave problems with a boiler or piping to a professional. A steam radiator has a small air vent near the top that emits bursts of steam when the radiator heats.

Steam systems cycle between hot and cold. Most are connected to only one pipe at the floor, but some have two. You can dismantle and service a steam radiator valve if the boiler is off. Hot water radiators are connected to two pipes at the floor. Prestart Checklist Time About two hours, plus time for finding the parts Tools Groove-joint pliers, pipe wrench, screwdriver Skills Familiarity with your system Prep Turn down the thermostat so the boiler will not come on while you work Materials Radiator valve replacement parts or a new valve, strand packing, pipe-thread tape. Heat recovery ventilation. Energy recovery ventilators (ERVs) are closely related, however ERVs also transfer the humidity level of the exhaust air to the intake air. Benefits[edit] As building efficiency is improved with insulation and weather stripping, buildings are intentionally made more airtight, and consequently less well ventilated.

Since all buildings require a source of fresh air, the need for HRVs has become obvious. While opening a window does provide ventilation, the building's heat and humidity will then be lost in the winter and gained in the summer, both of which are undesirable for the indoor climate and for energy efficiency, since the building's HVAC systems must compensate. UK building regulations require one air change every two hours (0.5 ACH).

Technology[edit] HRVs and ERVs can be stand-alone devices that operate independently, or they can be built-in, or added to existing HVAC systems.

I really value all of your opinions, and would like input as soon as possible. Brian in Swampland. Contact Spacepak. How to Maintain Hot Water Heating Systems. Hot water heating systems need a little maintenance, like venting the radiators and draining the boiler, to keep things running efficiently. Gravity and hot water furnaces are not often installed in new homes today, but similar systems with the old cast-iron radiators throughout the house were fixtures in homes built around 1900, and some of them are still working.

Clanking, popping, and gurgling as they swing into action whenever the thermostat detects room temperatures dropping, they provide a relatively steady flow of heat without the drafts you get in forced-air furnaces. Hot water systems are closed, meaning that the water constantly circulates through the pipes and into the boiler. Newer units have many zones with two water pipes linked to each zone: one circulating heated water to the rooms and the other returning the much cooler water back to the boiler to get reheated.

To maintain a system, you should lubricate the circulating pump motor. Hot Water Piping Systems- Buda, Texas. How to Maintain Hot Water Heating Systems. HOW TO DRAIN YOUR HEATING SYSTEM - Pressurised - PLUMBING TIPS.
