Pipe World 2/2019
THE UPONOR INFRA CUSTOMER MAGAZINE » ISSUE 2/2019 FISHGLOBE REVOLUTIONISES THE FUTURE OF PLASTIC STRUCTURES FOR MARINE CONDITIONS Page 6 SAFEGUARDING THE DRINKING WATER IN URBAN AREAS IS CRITICAL Page 8 FLOW MEASUREMENT REVEALS LEAKS IN THE WATER SUPPLY NETWORK Page 12 Dear reader, he water supply and wastewater infrastructure in many regions across Europe is ageing. Despite the high quality of drinking water in the Nordic countries, the condition of the old pipe networks poses challenges. For example, Tin Finland most of the network was built between 1960 and 1990 and in the biggest cities parts of the network are over 100 years old. According to a recent study in Finland (ROTI 2019), 12% of the sewer network and 12% of the potable water network has deteriorated and there is an increasing need to renovate the old networks to both ensure water quality and minimise water losses. In Finland, 68 million m3 of mains water is lost every year and a substantial part of this is due to leakages (SYKE 2018). In Sweden, the total leakage of clean drinking water is about 15% on average, corresponding to 99 million m3 (Svenskt Vatten 2019). This is not only a waste of clean drinking water – resources used to collect, treat and pump the drinking water are also wasted. Losses of water, and in issue 2/2019 particular leakages, are relevant for distribution network efficiency in all European countries. New innovations are needed to help solve these challenges. On p. 12, you can read about how our new Water Monitoring Services are helping the city of Pori in Finland to monitor 4 In Brief 16 Industrial its leakages. -

Underfloor Heating Systems Are 100 W/M2 for Concrete Floors and 70 W/M2 for Timber Suspended Floors
INSTALLATION INSTRUCTIONS ONE LARGE ZONE Unit 1 79 Friar Street Worcester WR1 2NT Tel: 01905 616 928 Fax:01905 611 240 E-mail: [email protected] Website: www.underfloorheatingsystems.co.uk 1. Installation Read this entire document first! Pipe distance for concrete floor is c/c 200 mm to c/c 250 mm and for timber suspended floors c/c 200 mm. Pipe to be 100 mm from the walls. Always go with flow to the cold spots first. See hand sketch for typical layout. Max loop length is 110 m. Max loop length is 110 m. If the pipe comes in a 200 m coil, it is sometimes much easier to work with the pipe if cut in half, ie 2 pcs of 100 m coils. Also we recommend two people for fitting the pipe, one person that holds the coil and another person to clip the pipe into the insulation. Fix the pipe to the insulation with the clips provided. You need approximate 1 to 2 clips per metre of pipe. The manifold and control pack should always be located centrally in the building. The PRT room thermostat timer controls the pump. Note, see system layout provided in this document for typical layout. Also, see wiring diagram provided. The system needs to have independent control from the boiler, ie S-plan system with a two port valve. Try to use all the pipework supplied. You will usually have waste. The pipe is marked every metre so you know when it is time to go back to the manifold. -

Underfloor Heating Installation Guide Installation and Maintenance Guide Installation and Maintenance Guide
UNDERFLOOR HEATING INSTALLATION GUIDE INSTALLATION AND MAINTENANCE GUIDE INSTALLATION AND MAINTENANCE GUIDE CHAPTER 8 - UNDER FLOOR HEATING (UFH) 8.1 General Guidelines Thermal resistance of wood varies with the species but is in the order of 0.13m2 K/W. Wood naturally reduces heat transfer through the whole floor construction and thus wood flooring should only be considered over an UFH installation with full prior consultation with the heating engineer. Please also note that most Ted Todd engineered floors are supplied with a moisture content (MC) of between 8% - 10%. After a period of time under an UFH installation the MC of the wood may drop to 6%-8% or lower. This could cause some shrinkage in the floor boards. Similarly, if the UFH system is switched off after installation (such as in the summer) the M/C of the floorboards may rise again causing some width expansion. For this reason, the MC of the wood floor must be carefully checked before installation and if necessary, extra acclimatisation should take place. Similarly, allowance should be considered for some expansion of the wood in case the heating system is switched off and the site’s humidity rises again. All of our engineered floors are suitable for installations with UFH systems. You must check with the manufacturer of the UFH system to ensure that the system can be properly controlled to ensure the maximum temperature of the timber floor (at any point) will not exceed 27°C. All installations of Ted Todd wood floors over UFH systems must be accompanied by the installation of the Ted Todd Fidbox monitoring system allowing the temperature and humidity of the wood floor and sub-floor to be monitored and recorded. -
Solar Thermal from Timóleon
Introduction to Solar Thermal from Timoleon to Solar Thermal from Introduction Solar Thermal from Timóleon 2014 TN21 Solar Thermal Timóleon Solar Thermal Systems are able to collect the sun’s energy so that it can be used for both heating and hot water. All Timóleon hot water systems enable the homeowner to benefit from RHI payments as well as making significant savings on their energy costs. Energy from the sun Solar thermal is very effective as an alternative energy source. In the UK we receive up to 1200kWh (units) of solar energy per square metre of land each year with Contents energy available even on a cloudy day. Compare this to the annual heating and hot water consumption of a 3 bed house of about 10,000kWh and it is clear that solar can make a significant saving to the energy costs if collected and efficiently used. Introduction to Solar Thermal pages 2-3 The energy collected from solar thermal can be very useful however during the spring, autumn and winter this is often at a low temperature. For this to be useful the underfloor heating needs to run at low water temperatures and have a control Hot water system that is able to make intuitive decisions based on how cold it is and the pages 4-7 temperature of the stored water. This delays the need to use a boiler or heat pump until there is no useful energy available from the solar panels. Timóleon’s SunCylinder does just that, enabling up to 40% of the total house heating load Heating / Hot Water to come from solar thermal energy.
