ing a brief review of some of the engineering and
economic aspects of this development. The
emphasis will be placed on general aspects and
future plans rather than on descriptions of
present installations.
The most important future plan, the Krýsu-
vik-project, will be discussed in some detail at
the end of this paper. On the other hand, power
production projects will be omitted in the main
discussion. For this topic the reader is referred
to a paper by Einarsson (1961).
For a description of the main existing district
heating system, the Reykjavík Municipal District
Fleating Service, the reader is referred to the
description by Sigurdsson (1961). The technique
of drilling for hot water and natural steam is
reviewed by Karlsson (1961). A review of the
physical characteristics of natural heat resources
in Iceland is given by Bodvarsson (1961).
2. REVIEW OF PRESENT UTILIZATION
AND GENERAL PROSPECTS.
The Reykjavík Municipal District Heating
Service distributes natural hot water for domestic
heating for approximately 40,000 inhabitants
of the city. There exist district heating systems
of a similar type in 4 small communities, Olafs-
fjordur and Saudarkrokur in the North of the
country and Selfoss and Hveragerdi in the
South. Moreover, a number of central heating
svstems has been installed on farms lying in the
vicinity of thermal areas. The total number of
people outside Reykjavík living in houses heated
by natural heat is now about 5,000, giving a to-
tal of 45,000 for the entire country.
The total floor-area of the green-houses heat-
ed by natural heat is 95,000 square meters ancl
the total number of swimmingpools is about 80.
The total consumption of fuel oil equivalent
to the present annual consumption of natural
heat can be estimated on the basis of the above
figures. The results are given in TABLE I.
At present the city of Reykjavík has about
74, 000 inhabitants. The communities of Kopa-
vogur ancl Hafnarfjordur, lying respectivelly 5
km and 10 km south of the city, have a total of
13,000 inhabitants. Thus the Reykjavík area has
at present a total of 87,000 inhabitants. The ex-
pected total for 1970 is 110,000.
At present there are therefore in this area
about 47,000 people living in houses not served
