Presentation Low-H2O The Radiator Factory 2002-2003

HEATING TECHNOLOGY & SOLUTIONS

Evolution towards the lowest water content Bad insulation Poor insulation Average insulation 1930 High insulation 25 litres 1960 12 litres 1980 7 litres 2002 1 litres

New construction technology Higher insulation 1. New construction technology Higher insulation New heating concept: Low Mass Radiators & installation

1980:Old house and heating system

The house Poor insulation *** High heat losses Cold radiation Draughts

2000: modern house and heating system

The house GOOD INSULATION MINIMAL HEAT LOSSES NO COLD RADIATION NO DRAUGHTS

Why the need for a low radiator mass? 1930 1980 2002 2000 watts 600 watts 80 watts Average insulation Poor insulation High insulation

from copper with lower water resistance Larger air vent chamber 1. COMPACT STRENGTH Brass collectors for better water injection control and flow system with lower water resistance Parallel flow from copper with lower water resistance Larger air vent chamber for improved air vent Drain Cock New expansion collar for silent operation Corrugated aluminium fins with increased area and smaller interim distance

AS A COMPARISON High water temperature element (90/70° C) 1. COMPACT STRENGTH High water temperature element (90/70° C) larger fin distance smaller contact area smaller aluminium area N-value approx. 1.4.

2. MAXIMUM COMFORT 3X faster reaction time Correct room temperature 1/10 of the water content 3X faster reaction time Correct room temperature

RESPONSE TIME COMPARISON

3. MINIMUM CONSUMPTION Practical trial: Energy saving of 10% (University Portsmouth - UK) Full operating temperature of the C.H. system in approx. 10 min. (90/70°C)

4. HEALTY HEATING Less dry air, no risk of damp problems Evenly distributed air circulation: Less dry air, no risk of damp problems Better temperature distribution with a lower issuing air temperature No heat radiation

TEMPERATURE DISTRIBUTION COMPARISON

5. SAFE HEATING Handicapped, elderly people, children Contact temperature Of max. 43°C, even with a high flow temperature of 90°C Satisfies the latest safety standards
