Space Heating – Wet Systems

Energy Savings for Wet System Space Heating with Envantage

Improvements to wet central heating can save £1000s


Businesses who make simple improvements often stand to save thousands of pounds per year.

In many commercial properties, heating is provided by a hot water central heating system, with a boiler providing the heat generation.

This space heating often accounts for a large proportion of energy use for commercial businesses.

Opportunities for cost savings are therefore often substantial.


How Are You Wasting Heat?

There are numerous sources of inefficiencies:

  • Boiler Efficiency – Old and inefficient boilers are one of the largest sources of energy wastage in central heating systems. Boiler efficiency has improved dramatically over the past decade, with many modern commercial units now boasting seasonal efficiencies in excess of 95%. Older boilers generally range from 65% to 85%.
  • Heating Controls – Temperature and time controls are an important aspect of any heating system, and another source of energy waste when not managed correctly. Every 1 degree C above the required temperature results in an 8% increase in the energy costs.
  • Heat Transfer – Water is a poor heat transfer medium for several reasons, including a high surface tension and insulating bubbles in the system. These issues can be easily resolved using low cost measures, and result in energy savings of between 10% and 30%.

Space heating is an essential aspect of many businesses, and is often a source of contention between staff. Ensuring that your heating system is maintaining a suitable working environment for staff whilst performing to maximum energy efficiency is often a difficult task.

Opportunities exist to improve both energy efficiency and staff comfort levels, by improving wet central heating systems. Talk to one of our consultants today to find out which steps you should take.
