Kelcroft designs, supervises and manages a wide range of E&M engineering systems for the built environment including a particular specialty Steam and Condensate systems primarily used in the hospital, healthcare, manufacturing process, catering and industrial sectors.

Optimise steam and condensate systems energy use



Kelcroft provides you with solutions for the built environment, that others can't provide, we design, energy smart Steam and Condensate systems, including piping, heat exchangers and boiler plant.

Optimise steam and condensate systems energy use



Our wide range of experience includes consultancy and advisory services for steam and condensate systems, covering hospitals, cook-chill, steam boilers, steam-to-water heat exchangers, steam control, steam traps, conditions surveys, autoclaves, sterilizers, and catering equipment, laundry and industrial process steam applications. We help organisations conducting:

  • Design of Steam systems
  • Steam energy audits link
  • Steam Trap Survey link
  • Efficient use of steam


This expertise allows us to offer valued added steam and condensate energy conservation advice and solutions that lower fuel and operating costs.

Steam Condensate Water Recovery

After using the latent energy in your steam system the by product high grade hot water, is known as condensate.

Condensate is a valuable resource, it is vital for an energy efficient plant to return the majority of the condensate back to the boiler plant hot well for re-use. Increasing the quantity of condensate returned to the boiler plant has several advantages:

  • reduces raw water demand, saves water
  • avoids heating cold water, lowering fuel consumption
  • reduces chemical treatment


Condensate is considered to be high grade energy, often 70-80 degC at atomospheric pressure, this waste heat energy can be used for waste heat recovery, for example pre-heating hot water, or even air-conditioning.

Return How Much Condensate?

How much condensate should be to returned to the steam boiler plant, is a good question.

In a perfect world all, 100% of the condensate should be recovered and returned to the boiler plant for reuse, lowering energy costs by 25% (dependant on the boiler plant) and the related water and chemical treatment costs.

Inevitably there are some obstacles, including leakage and losses from the steam system, losses from the condensate system, or perhaps a portion of the condensate is contaminated and cannot be reused.

A good rule of thumb for steam systems target returning 80-85% of the condensate to the boiler.

Steam Generators

The energy efficiency steam generation is a critical aspect to optimise steam and condensate energy use.

Whatever fuel is used, oil, gas, or electricity its important that the boiler or generator creates steam at the correct conditions, pressure and dryness, using the minimum quantity of fuel. And the capacity matches the type and character of steam load required by the processes.

The energy efficiency of all the steam generators should be monitored and recorded frequently. If the steam is purchased, it important to understand the condition of the steam delivered and for processes sensitive to steam dryness, e.g. autoclaves, to know the steam dryness as delivered.
