When the top of a radiator is cold during operation, either air or hydrogen is to blame. Hydorgen gas builds up as a by-product of electroytic corrosion and is flammable (due caution is required).

If deposits of black and red sludge and timescale build up to a point where heat transfer is severely restricted, the boiler can overheat and fracture.

Like any working part of the system, radiators are prone to corrosion from installation debris and can fail within a few years. New systems must be pre--commission cleansed and protected and existing systems should also be thoroughly cleansed and protected.

The abrasive and magnetic properties of black oxide sludge increase shaft and bearing wear in pumps and valve actuators, causng them to either stick or fail.

Without treatment, corrosion debris will accumulate ni the boiler causing increasng Limescale deposits, reduced heat transfer ands up to a third of the fuel bill going to complete waste.

The familiar cool low central area of a radiator indictaes a build up of black sludge sediment taht restricts flow and reduces heat.

A combination of loose gland nuts, failed or failing O rings and poor packing around the stem of the radiator are usually to blame.

Heating and Plumbing Services utilises only the best and state of the art equipment for each assigned job.
The Fernox Powerflow is a powerful acid-proof flushing pump designed to make short work of cleaning boiler and radiator systems without removing radiators.
It can also double up as a descaling pump for heat exchangers. Powerflow saves time on site; when used in conjunction with Fernox Superconcentrate System Cleaner and Neutraliser, only one visit to site is required to powerflush & complete central heating system.

• Removes sludge and scale from Central Heating Systems

• Performs separate Boiler Descaling

• Overcomes Boiler noise and circulation problems

• Reversible flow action to ensure thorough system cleaning

• Complete system clean in one visit

• High flow, low pressure

All of our products are independently tested and accredited as exceeding the minimum SEDBUK efficiency requirements and comply with Building Regulations Approved Document L1A, L1B for England and Wales, the Building Standards (Scotland) Regulations Section 6, Part F Northern Ireland and Part L Republic of Ireland.
Warmflow boilers are covered by a 1 year parts and labour warranty on the boiler and controls and 5 years on the heat exchanger. Optional extended warranties are available providing cover for a full 5 years.
